So, here's the situation. While I was lining up at a bank, I graciously let this one really hot girl in front of me. (there was nobody else, and she smiled at me too) So, I'm standing behind her and she's transferring some cash to some person and the bank teller asks her for her phone number. The HB tells her cellphone number outloud and I just happen to have an awesome memory for numbers.
I called after an hour or so, and I confirmed that it's her. Now, I don't want to act like a creep by telling her that i was eavesdropping at the bank. Any ideas as to what should I do about this? I only know her name and her phone number.
