1. Not showing up to work things because you're so busy and so tired and just can't today. This was a fun thing that worked (for the most part) with classes and professors, but definitely not with your job or your boss.
2. Being on the same schedule as your best friends. In the Real World, it's not possible to go on ridiculous adventures on a whim or binge watch shows together whenever you want. You and your BFFs are now separated by miles and...work.
3. Designing your schedule so that you have nothing to do before 11 a.m. In college, you did your best to avoid an 8 a.m. class that met two days a week. The Real World is an 8 a.m. class that meets five days a week, and you always have to show up (sorry) (I didn't make the rules).
4. Taking mid-day naps. If you were big on mid-day naps, this is so very sad. The good news, though, is you can try to work at Google! They have nap rooms.
5. Having a three-day weekend every weekend. Scheduling no classes on Fridays meant your weekend shenanigans began on Thursdays (yet you still thought weekends were so short). Prepare yourself for how a two-day weekend will feel.
6. Going hard on Thirsty Thursday. Real World Thursday = two drinks at happy hour and then you're in bed by 9, which is when you used to start pregaming in your heyday. Yep, you are officially OLD.
7. Wearing sweatpants or shorts every single day. This means you cannot wear a baseball hat to hide your greasy hair either. Dry shampoo is your post-grad BFF.
8. Having an endless supply of clothes to take while your roommate's in class borrow. Now you're going to be building your wardrobe with your own paycheck.
9. Not having to buy Real People adult clothes. Wearing your tight bodycon dress and 6-inch platforms to work isn't going to fly. Club clothes are out, blazers are in.
10. Facing minimal consequences when handing something in late. It was no big deal when you started a paper five minutes before it was due because the worst that could happen to you was that you lost half a letter grade. If you mess up work deadlines in the Real World though, you're more likely losing your job.
11. Having an excuse for not having a job. When you were in college, maybe you could get away with telling your parents that "school is my job." After college, though, your only job is to have a job.
12. Posting fun drunk photos to your Instagram. Your Real World Instagram is going to be filled with pictures of you in your new Real World Life. You're about to go from posting pictures of you doing a keg stand to you holding your new business card.
13. Going on summer break. Or any breaks, for that matter. You'll have vacations, but they won't involve 500 of your other "friends," and you definitely won't be off for three months at a time.
14. Picking the easiest person to work for. In college, you took easy classes and picked lax professors to boost your QPI, but you probably didn't get much out of them. If you have an easy boss IRL, you won't learn anything and your work life will definitely be boring.
15. Dropping in to visit the campus nurse whenever you feel a pang of hypochondria. You actually have to, like, find a primary care physician, schedule appointments, and possibly pay out of pocket for services now.
16. Not caring how much your pure existence costs. Gone are the days when the 'rents paid for everything you needed to live. Now you have to fend for yourself. When you get your first paycheck, you are going to feel like a boss lady, as you should. Buuuuuut then you'll see where all your money goes: taxes, rent, food. You're going to want to take a seat and call your parents to thank them for paying for your existence for 22 years.
