1. The ones who never stopped overachieving

These people were the ones who took full AP’s and IB’s in high school, and were always there to send you a copy of their math homework a period before class. They excelled onto an ivy league, and you can’t wait to hear about how their time at school was.

Unfortunately, as the summer treks on, you figure out that you never will. They go straight from school to a mission trip abroad or working as a campaigner for Hillary, fueled by their go-getter attitude and caffeinated chutzpah. I look to these people with amazement, but also with a sigh of relief that I got away with sleeping for 3 weeks after I got home from school.

2. The ones who clearly peaked in high school

You know who I’m talking about. These are the people who had such a good time in high school that they’re choosing not to leave- whether its by maintaining a weirdly close relationship with girls two grades below them, or still refusing to socialize with anyone but their close friend group at parties.

These people were so placated in their comfortable high school personas that they refused (or were unable) to break out of their shell come college- resulting in a bad first year of college and a craving for their high school glory days.

3. People who made no friends in college because they were mean in high school

Especially when the number of your graduating class fails to dip into the triple digits, it’s hard to be picky about who you interacted with in high school. That meant grinning and bearing it when you ended up being partners with the notoriously sassy girl.

The great thing about college, however, is that you’re given the opportunity to meet so many new people and not be forced to be friendly with everyone. That can be a rude awakening to the people who glided through high school with an attitude based on passive aggressiveness and ignorance.

Come fall, they’ll realize that their arrogance should have been left at graduation.

4. The ones who disappeared

My second favorite thing to do is stalk my high school friends’ college lives. My first favorite thing to do is stalk the college lives of random people. Procrastination comes in many forms, and mine revealed itself at 2 am in the library when I’d suddenly wonder how that one girl in my math class was holding up.

There is a good amount of people who I’ve stumbled upon, however, who have no pictures of themselves tagged on Facebook from college. This absence echoes back at home- mention their names at parties, and everyone will be just as clueless on what happened to these people.

Be prepared for people who will come home from school and not want anything to do with their fellow classmates. This is completely understandable. Leaving high school is a natural disaster- it’s chaos, and once the debris settles, you really only care about reconnecting with your close friends.

5. The boys who you thought you'd have gotten over

“This won’t even matter when I’m in college. There’ll be so many hotter, more mature guys there,” you reassured and high-fived yourself last summer when mourning a failed rendezvous with a cute boy. That’s what I thought, too.

However, when coming home after your first year, its amazing how easy it is to forget the college romances that you spent all year maintaining and grooming. It’s also amazing how easy it is to remember how much you liked talking to your old classmate, or notice how much they hit the gym that year.

Soon enough, you’ll forget those hot D1 athletes from school and instead spend high school parties reconnecting with forgotten flames. It’s hard to fully shed those juvenile infatuations that leave you feeling young again.
