An Art Teacher (Long Term 5)

I over heard the following conversation today in one of my high school art classes.

Student 1: Wait, who's Bill Murray?
Student 2: You don't know who Bill Murray is?  Dude, he's a comedian.  He was in Space Jam.

I spent time after school mounting some student work on large sheets of cardboard, so that I can hang them in the hallway.  Just as I was getting ready to head to the other end of the building to grab something, three students walked in.  One of them is a very avid art student, and someone I know I can trust.  I didn't really know the other two girls with him, but they seemed trustworthy.  He wanted to show the girls a project he was working on.  I told them that they could stay while I went out, but to just close up the room if they left.
While at the other end of the building I ran into another teacher, and we started chatting... 30-40 minutes later I walked back into the art room, only to find that the three students had CLEANED the place.  I had been doing a pretty good job keeping stuff picked up, pretty much in the same condition I found the room.  These kids put everything away, clearing off all of the counters and organizing the supplies.  I was so shocked that I probably seemed ungrateful, just because I had no idea what to say... "thanks" just didn't seem like enough.
