Oh, gosh, I really, really don't know why I don't like the last line. I guess it just seems a little too... blunt? Like everything is just spelled out rather frankly. I'm being unfairly picky, I'm sorry, but I just thought I'd mention that. :)
Ahh, I love this song and this was really amusing. The last line, "I was going to write a song about this girl." kind of rubs me the wrong way, but that's just because I'm a picky bastard, haha. Love the whole basis for the song, though, it was lovely. :)
Okay, so I don't really know who this is about, but it was interesting! I really like the rhyme you had going in the summary. I've never written a drabble, I'm really wordy with my descriptions and conversations, but you make drabbles seem easy. You pull the reader in with just a few words and that's an amazing talent. You're a great writter.
I was just... left wanting more. Like this was a good start, but that's all it was - a start.
