If you left your hometown to attend college, winter break is likely a bittersweet experience.

On the one hand, you’re free from the stress of campus parking for an entire month. On the other hand, your nightlife will downgrade to watching Seinfeld reruns with Nancy and Carl (or whatever your parents’ names are).

But the biggest buzzkill will come in the form of unexpected encounters. People you haven’t thought about in months or years will suddenly demand your attention, and the contextual shift will be as jarring as a Jersey Shore episode in the Uffizzi.

So this year, when you trek home to Pleasantville, be prepared for these unpleasant scenarios:

Your old Spanish teacher

Nancy sends you to Wegman’s for milk and waffles. But before you’ve even hit the frozen foods section, you’re accosted by your old high school Spanish teacher. She’s as ebullient as ever – over-accessorized in jangly bracelets and a scarf from the Fran Drescher collection.

She asks you how you’re doing and something else – in Spanish, of course – so you have no idea what the #*@! she is saying. You default to your old standby, “Claro que si!” But this does not suffice, as she tilts her head and widens her eyes in pedantic dismay, waiting for your brain to register some abstract vocabulary word from sophomore year.

You could stand there for days, decoding context clues and abiding her 19 variations on the original question – each offered with growingly transparent gestures and elongated vowel sounds. Or, you could counter with an approach that wouldn’t have worked in 10th grade, but somehow carries credibility now. Tell her your cat is sick. Hold up the milk as evidence of cat-related strife. And most of all, remember that times have changed. She no longer has the power to exclude you from the Cinco de Mayo flan and gazpacho party.

Your random high school classmates

You know that shopping at hometown Target is a bad idea, but something crucial is bound to fail at a time-sensitive moment. Your family dog will eat the remote control right before the Fiesta Bowl. Carl will clog the toilet on New Year’s Eve. As you set out in search of remedies, you promise yourself you won’t dally by the $4 DVD display, and you actually believe that you can manage this trip without some awkward encounter. You are wrong.

You’ll inevitably cross paths with a former high school classmate. Probably the one who threw up on the marching band’s bus trip to Washington D.C. after you bet him he couldn’t eat 100 chicken McNuggets. Or else, the one who overheard you comparing her prom dress to a sausage casing, back in 2008.

To make matters worse, this person will be toting something inexplicable, yet unavoidable – like 12 gallons of bleach – in her shopping cart. When she says, “oh hi,” with a tone of resentment and superiority (because you caved to the temptation, and are now standing by the $4 DVD display with a copy of Hope Floats in your hand), don’t give her the satisfaction.

Pile 12 absurd things into your own cart. Claim that you’re late for the class reunion. It doesn’t matter that there is no class reunion. By the looks of things, she has messier fish to fry anyway.

The bratty kids you used to babysit

Going out to dinner used to be a safe, enjoyable experience. But during winter break, local restaurants become three-course landmines. Carl and Nancy tell you you’re being ridiculous, but sure enough you spot the kids you used to babysit, smoking cigarettes and throwing rocks – like some 1950’s street gang – outside of Applebee’s.

You only recognize them because the snot-nosed one, who as a five-year-old insisted on wearing his cowboy boots to bed, now walks with a duck-toed gait.

They will snicker as you pass. You are probably infamous in their household, thanks to the time you called their parents home from an opera because the radiator was making sounds like small animals were trapped inside. Do not feel defeated by these two-bit backyardigans. Instead, ask to bum a smoke, and offer to read them a bedtime story in return.

You don’t really have to smoke the cigarette (or read the bedtime story). But in doing so, you’ll have succeeded in reminding them how much you know about their bedwetting habits.

Your ex-boyfriend or girlfriend’s parents

Church, temple, mosque: wherever you go to worship, most religions value forgiveness. During winter break, most religions also smite you with the karmic backhand of a holy run-in with your ex’s parents. Decidedly, this was the relationship – of all your relationships – that did not end well. Guidance counselors got involved. Goldfish were kidnapped. At one point Carl had to coax you down from an attempt at billboard graffiti.

These parents do not like you. And the distance of a few years has not softened their hearts to your teenage misdeeds. When the time comes to acknowledge your fellow parishioners, fake an uncontrollable coughing fit. Excuse yourself out the nearest exit, and say a little prayer that God understands why you had to reclaim that goldfish.

Your family dentist

It’s not clear why the guy who cleans your teeth thinks he has custodial rights over your mouth and its contents, but if you happened to pierce your lip or your tongue while away at college, your family dentist will NOT let the matter slide.

Winter break is the ideal opportunity for a 6-month checkup, along with 86 questions from Dr. Intrusive. He’ll present all manner of scare tactics: telling you that a lip ring causes chipped teeth, that a tongue ring is a recipe for thrush, that both are guaranteed rejections if you ever decide to pursue dental school. (Dentists also assume every student considers dental school.)

And then he’ll delight in your bleeding gums, speculating that you could floss more often with the time you spend polluting your oral habitat. Don’t apologize for anything. Just grab your free toothbrush, and make a point to “miss” his little spit sink after rinsing.

Your cranky neighbor

Winter break will not be complete until an untimely trip to the mailbox results in a face-off with your joyless neighbor – the guy who called the cops on you that summer, when you had a medium-sized, somewhat contained house party while Nancy and Carl were learning to paddle surf in Florida.

Joyless Jennings will scowl at your clothes, your haircut, your upbeat countenance, and ask something subtle like, “you got kicked out of college already?”

Tell him you never went to college in the first place. Tell him you’ve spent the fall chasing amateur poker tournaments, and that you’re using your winnings to buy your parents’ house – a wedding gift for your new husband and your five “sister wives.” That’ll teach him.

Who are you hoping to avoid this holiday season? And is it ever okay to just pretend you don’t recognize a familiar face?
