I went up to this girl in the club and used the direct opener -
"I walked past you a while ago and I thought you're really pretty and I just wanted to say hi"
She smiled and gave me her name and we talked for a bit. But......when I asked her for a dance she said "I'm with friends". I wished her a nice evening and left.
Now I understand that I pulled the trigger too quickly. So, experts - how to deal with this.
