Trash on Campus

So, I guess I'm kind of mean sometimes, like when I find a piece of wadded up paper on the ground and it is some kids' schoolwork, I will see if the kids' name is on it and take it to them like it is something important that they "lost". I don't give them a speach about littering or anything, but I make a big deal about it, like they should thank me, as if I have recovered their missing property.
