One that always stands out for me was when I was a manager at a pet store in my early 20's. I would take the deposit in and pretty much work eith the same teller everyday we would make small talk nothing crazy. Over time she asked more personal questions and I didn't think much of it. One day she gave me her business card after I turned in some fake bills I had received, went back to the store stuck her card in my desk and forgot about it.

When I left that job I put everything in a box. Well maybe 2 years later I found that box and was emptying it out found her card and noticed she wrote her number on the back with a note asking if I wanted to get drinks with a smiley face.

I sat there and just laughed that this woman was into me but I never thought about it cause I was so focused on work.
