Today.

Today I went to the supermarket and saw this girl. She looked at me twice before and I got an impression that she somewhat liked me. After a few minutes I kept seeing her about and I chose one time to go over and talk to her, truth be told I don't know how to ask for numbers I never have. So I went over to her saying 'excuse me' (about two times) then saying 'sorry' and got her attention; after saying this

I said: 'first of all hi my name is .. what is yours'

Her: 'Olivia'

Me 'I was just wondering is it possible I can get your number'

Her: 'Sorry I have a boyfriend'

Me 'Oh'

Then she just walked off, I mean obviously I do not get signs and I cannot read them but I felt and feel so embarrassed about the situation. I haven't felt this bad in a while like why did I do that and why didn't I try not to. I'm so stupid.
