Let's face it - being a kid has the major perk of not having to spend your own money, your own money that you earned. You didn't have to make your own dinners, or go grocery shopping, or do all your laundry, or wash the dishes. Life seemed easier. And once you start "adulating," you'll have to do pretty much all of these things.
1) Going grocery shopping
First of all, getting to the grocery store can already be a challenge; if it's pretty far from where you're living now, and you don't have a car, your life will be a bit harder to supply more food at your place whenever you need anything.
2) Cooking for yourself
The cliche move of a college student is to live off of ramen noodles and Domino's Pizza. No one actually feels motivated enough to cook a full meal after a really long day of classes and/or work.
3) Doing laundry
The amount we have to pay for a few washes is hard enough. Then you have to wait until your wash is ready to be thrown in the dryer, and the whole process can take up a chunk of your entire day, depending on when you do laundry.
4) Paying Bills
The biggest part of being a rreal adult - handling finances. Watching your account spike from your last generous paycheck, to decrease from the withdrawal you had to make to pay off that bill is painful. And if you forget to pay off something...well, good luck.
5) Getting a job
A large percentage of college students feel inclined to get a job or two to pay for rent and other necessities. The process of applying is annoying itself - the cover letters you have to write can be so time consuming that you didn't have time to finish that paper that was due. The interview, depending on the job, can be stressful too because now you have to put some effort into your appearance for the day.
