The primary thing I've learned from this? People pick their noses a lot when they think they're not being watched.
* I put on my name tag, which I almost never wear, so they know I'm legit! And if anyone asks me not to take a photo of them, I won't, but nobody's asked it so far. We asked the university about the legalities involved in taking photos of students, and it turns out they all sign a document when they enroll that gives blanket permission for their photos to be taken and used for University business at any time. I still wouldn't take a photo if someone asked me not to, though!
