You constantly forget that you're supposedly a grown-up now.
You always put the USB in upside down on your first try, flip it, and then realize you had it right all along.
Every time you've drawn a particularly good curly brace ( } ) you are inappropriately proud of yourself.
Whenever your ears start randomly ringing, you wonder if someone is blowing a dog whistle and you're actually a werewolf.
You set your alarm an hour before you have to wake up so that you can go back to sleep.
