Your at school. The bell rings. A mob of people rush out, nearly knocking you down. Woo-Hoo! time to go home. You look around for some friends. You see your friend Christina across the quad. You like Christina alright, but she's a bit of a wild one. You know, home isn't really that far. It's a nice day. But then you remember hust how heavy your backpack really is. Do you try to hitch a ride with Christina or do you rough it home?
