When I was in sixth grade, I asked Alese Watson, who was in fifth grade at the time, if she would go out with me. I didn't ask her myself, of course; this was a time when it was socially acceptable, even expected, to have someone else act as a go-between. So I sent word that I'd like to go out with her, and she sent word back that she agreed.
We went out for about a week. Then she sent a go-between to tell me that she was breaking up with me. Why? Because in that time, I hadn't actually spoken to her. This, I had to admit, seemed like a pretty reasonable justification. I mean, it simply hadn't occurred to me that I ought to be talking to her; but looking at it in hindsight, it seemed like a pretty normal expectation. So my response was basically, "Oh, okay. Sorry." And that was pretty much it.
Also, this is probably funnier if you've ever met me in person.
