Sprinting to bed after turning off the lights.
You know monsters aren’t real, so stop reverting to your 5-year-old self as soon as you flip the light switch.
Ordering off the kids’ menu.
First of all, you’re an adult with an adult appetite, so a small plate of chicken nuggets won’t suffice. Second, it’s tacky to order off the kids’ menu just because you don’t want to spend the money on an adult plate.
Refusing to brush your teeth before bed.
This is bad hygiene, and you know it. You also know that dental health is incredibly important, so brush your teeth before bed so you don’t need dentures by 40.
Taking a PB&J to lunch every day.
You might love PB&J, but the office isn’t the elementary-school cafeteria. Save these for a lazy dinner, and bring a more mature meal to work with you.
Throwing a fit when you don’t get your way.
It wasn’t okay when you were little, and it’s even less okay now that you're old enough to drive a car and have your own health insurance. It’s time to emotionally grow up, accept that you don’t always get what you want, and learn to deal with it.
Covering your eyes during scary movie scenes.
This was only forgivable when you were terrified by every little ghost story. Now that you’re grown up, either watch the entire scary movie or just don’t watch horror films at all.
Refusing to eat green vegetables.
Your palate has grown since you were 7, so stop refusing to eat broccoli, lettuce, and brussel sprouts. They’re good for you and just as delicious as your mom told you they were.
Cutting the crust off of your sandwiches.
If you want to be seen as an adult, then please for the love of all things delicious stop declining the best part of the bread. You’re missing out on so much flavor and texture!
Watching Saturday-morning cartoons.
These cartoons are not created to entertain those old enough to vote and buy alcohol. You shouldn’t be spending three hours in your pjs with a bowl of Lucky Charms watching cartoons every weekend.
Sucking on your hair.
This is a gross habit even for children. It’s even more repulsive when adults suck on their hair. Don’t do this if you want to keep your friends and a semblance of maturity.
