There's this guy I've been working with who I've developed sort of a crush on. Weve been thru a few meetings together, sent numerous emails, he's given me a tour of the new location (he works there and I am soon transferring to that location). we flirted a little when I've been in town but nothing really much. Anyways, I called him the other day and said, hi (his name) this is (my first name) and he waits a beat and than says "who?" To which I respond with my full name and then he laughs a little and then says oh, I didnt recognize the number. I have an unusual name, not like Megan or Kelly, so it wasn't like people with my name call him all the time. I also had just sent him an email an hour before. so why didn't he recognize it? Or could he have been pretending not to recognize it? If so why would he?
