At the moment I'm sitting in homeroom, which you might think is pretty boring but I beg to differ. There's a lot of things you can learn about people by eavesdropping . For example, I sit in between a set of twins and they're discussing what they want for Christmas. They guy twin wants video games and the girl twin wants a mandolin. Seriously, how many teenage girls want a mandolin for Christmas? Apparently she owns 7 different string instruments (9 before her dad sold 2 of them). I think that's pretty cool.
I don't know if you've ever seen any rendition of Sherlock Holmes (I recommend the BBC series) but I think it's really fun "Sherlocking" people. Like, trying to figure things out about people by just observing and listening to them, that's usually what I do when I'm bored.
