Sometimes I'm at work, and I'm bored, and I will send out a message to someone. So I have no issues with sending out an introductory email. And if I write to someone, of course I hope they write me back. However, as I know from personal experience, you never know who you're really talking to, so I don't take it personally if I don't hear back. I've talked to guys posing as girls, girls using other girls pictures, and of course the good old sudden disappearance while conversing. And a smattering of crazy too, which is always fun. So it's not worth getting upset over.
So that's just all to say that while I am a really fun, down to earth, respectful guy that you should want to say hi to, I'm not going to chase you. I very well might in a real world setting and I am far less cynical than this might lead you to believe, but what I'm really interested in is getting off this bullshit website and not running the mental obstacle course of proving to some girl who may or may not be the girl in the pictures why she should let me take her out.
