gotta' hate that. haha that happened to one of my friends, except we were at church, and it fell onto the pew in front of him. so he quickly picked it up and stuck it back in his mouth. I wasn't sure whether to laugh or be absolutely disgusted.
For me, it's either, I have my hand up for 10 minutes then the teacher answers it. Or, I have my hand up for a long time, then I give up and put it down. Immediately after the teacher calls on somebody other than me
