I was always scared to ask them too, probably 'cause I know I would hate to write a reference letter for anyone--I just wouldn't know what to write! But I suppose that when you're a professor or a supervisor or someone who gets asked to write those kinds of letters for people, you just get used to it. Wow, that was really quick, getting it the next day! Good for you. I actually haven't got mine yet 'cause I told them I wouldn't need it until a few more months. Yeah I asked like really early 'cause I was getting such good grades in their classes, I wasn't sure I'd be getting anymore grades like that (yeah I know, I'm a pessimist), so I wanted to talk to them about it so that when I actually did ask them in a few months, they'd remember me. Watch, they probably won't even remember me come September when I need it. They'll be like... and who were you? Just last year, really? Well, I guess we'll see.
