i've always wondered what amy meant by "you love blow and i love puff." now, i have two ideas on what she meant & feel free to share how you took it or if she explained it somewhere i haven't seen/heard.
1. blow aka cocaine is a quick high and puff aka marijuana is a engulfing high. so when she said you love blow, blake likes a quick relationship or hookup. then i love puff, amy wants more from the relationship than just a hookup.
2. when amy met blake he was already doing blow and she was more of a puff girl. she says before that love isn't enough and she always wanted to do anything he did otherwise he'd be there & she'd be here. so, maybe she felt that the love wasn't enough because she didn't do blow, which kept them two separate entities?
