I have an account, but I don't pay or anything. I guess if you pay you can actually email/contact them. Anyway, I'm really thinking about doing it because dang there are some hotties on there. More than you would find on some trashy "free" site.
You asked her if she wanted to grab coffee. Then you asked if the time worked. Then you asked if the place was okay. Then you asked if she'd prefer tea.
Four questions. Four chances for her to say no. Four signals that you're terrified of making a decision.
Plan it. Pick the place. Pick the time. Tell her where to meet you. She'll either show up or she won't.
Either way, you look like a man instead of a scared little boy.
