Just a quick question, it'll only take a minute or two!

About a year ago, this guy who was my friend asked me out on a bus back from a middle school trip. It was in note form, and nicely written, but I declined because 1. I can't date yet and 2. I personally thought that over the trip, we had become closer as friends. (I've known him since 4th grade, and I used to have a small crush on him from 5th to 7th grade, but it stopped after summer of 2011.) We kind of lost contact there and we haven't been on the same page since.

Whenever I think about the note, my heart flutters a little, but it leaves this sort of dread and I sort of just want to burn the evidence of it. I think I feel bad for rejecting him, but in the then-current situation, I had to. Also, it didn't feel right.

I'm not too worried, but I'd like to hear your thoughts. c: (note: I can't date until I'm 16, and that's a year from now)
