I have a group of students who seem to think it's very funny that one of them saw me having lunch with one of my colleagues a few times. This is not surprising, since she and I probably have lunch more days than not. (I'm reminded of an evaluation from a student years ago which said "I see him out eating all the time." I wondered if that one might have meant that I ate out way to often. Either that, or the student was stalking me.)
My students this semester like to ask how my date was and then giggle. I'm not sure if it's funny to think of their professor having a date at all, or that it's funny to suggest I'm going on a date when I'm not. I'm not sure why either would be that funny, actually. All I know is it baffles me and it feels very much like junior high (or earlier). But then students seem to get younger all the time. Why, every year it seems like the new first years are another year younger than me.
Come to think of it, by this point many of my students probably grew up with Harry Potter, which is in my recent memory. Ack, I just made myself feel old.
Nonetheless, my students' obsessions with my lunchtime habits are just plain weird.
