A student walked into 6th period carrying a guitar case. He asked me where he could set the thing during class.
(The students don't have lockers, so many carry around their gym bags or musical instruments as well as their backpacks. A student carrying a guitar is so normal that it normally wouldn't even merit a remark.)
I pointed to a spot at the front of the room. Then I wondered...
"What do you normally do with it?"
Student: "I've never had it before..."
I was getting ready to ask him what he'd been doing in a guitar class without a guitar all this time, but he continued before I could voice the thought.
"...It's not mine. I'm holding it for someone."
Student: "He paid me a dollar."
Me: "That's the going rate?"
Student: "I was hungry, so I used it to buy some chips. I was considering selling [the guitar that isn't his], but then..."
(The rest of the conversation veered off course, and I was no longer sure if he was referencing the guitar, his friend, the chips, or... Well, he's a freshman, so who knows what he was talking about.)
