I was at a bar (with a partner at the time, who was on the dance floor) and a girl came up to me and started a conversation about her college classes and her puppetry. I though it was cool! We had a good conversation and the girl's sister eventually pulled her away. My then partner came up and told me she was totally interested. I was like "Her? Nah, we were just talking about some cool hobby stuff!" She was totally into me apparently.

Note: My partner was not upset, she was a very sexually progressive person and even suggested I get her number. I'm a one person kinda lad though.
