Some awesome advice from Megan:
First thing's first: never ever try to figure people out. It's impossible. Let them explain themselves or just forget about it because as soon as you forget about something, you always get the answer.
Also, make sure you do your best in school. :)
Some awesome advice from Kelsey:
Never leave your locker open.
Never tell anybody your combination to your gym locker or locker.
Never leave your gym locker unlocked.
Get on your teacher's good side. :P
Laugh a little.
