Dan Dear Dan, I'm sorry to be the one to break this to you, but she is obviously not interested. Or she's playing really hard to get. In which case you should ask her out again. But really darling, you shouldn't fall for every nice woman who sells you something. Let me offer you a tip.

Besides, there are many nice single women out there. She can't be the only one.
