Students come up to me all the time having to go to the bathroom. I get like 10 a day. I wish they'd go during lunch or something (I have to) but I guess when the teacher lets you go to the bathroom, you don't waste precious socializing time going when you could be spending precious instructional time instead. However, I usually don't deny the students the right to go, though I may make them wait until I'm done teaching: the last thing I need is to have some kid pee on my floor!
Anyways, I had a student ask if he could go to the bathroom. "It's an emergency!" I hear this all the time from students who forget their hall pass. This student had his hall pass though, so I told him to fill out the date, location and time and bring it up to me for a signature. 5 minutes later, I noticed that he hadn't come up yet. So I walk over to him.
"You didn't get your hall pass signed. Didn't you want to go to the bathroom?"
"No, I don't need to go anymore."
This line always cracks me up. When you think about it, it's a funny statement coming from someone who swore it was an emergency. It's not like the urge suddenly goes away or anything. I laughed, told him that saying that was scary and left.
It never occurred to me that there is one time when you don't need to go anymore. When you've already gone.
Since I was cruising the opposite side of the room for most of the period, I didn't notice the large puddle that had formed under the boy. And he never raised his hand or said anything else. Until 20 minutes later. At the end of the period. He'd been sitting in a pair of soggy pants waiting for the end of class. Ugh. Needless to say, I sent him to the office and I'll think twice when the student swears it's an emergency.
