Your best friend from childhood lives across town, not across the country. You probably aren't woken up by 10 girls running up and down your hall at 3 a.m. every night. You can be involved in 15 different activities and handle them all. Nobody can laugh with you about the stupid things you did in third grade. You can be as immature as you want, and people blame it on your age.
Freshmen are peons.
Athletes still get major privileges. School food will always be disgusting. Cliffs Notes are still your best friend. Morning classes are hell, no matter where you are. Everyone has their own little group of friends.
