It's really hard to pick your nose when you're sitting in a computer lab and you're supposed to be working and there's this really cute girl on the other side of the room who might see you do it but you know she's not interested in you anyway and really she's probably not interesting and wouldn't care even if she did see you rooting around with half a finger in your skull and jesus why do you have to pick your nose in public anyway, that's what the walk to the tram's for.
