So today I rolled the dice couple of times. I did like 5+ approaches. 2 stood out. One was a very cute girl but she had a bf but we had a nice connection. And the second one was a very hot 25 year something hipster chick with stunning eyes in a smart shop (she is an employee there). I want to talk about this chick a little bit more. We talked about LSD and I just told some stories of my trips and I think I portrayed wide range of emotions on my face, more than I would liked too; and we created a very interesting bond. Unfortunately she had a bf, she told me that I didn't ask her, but I just kept talking and said  "I would have invited you to be my trip sitter if you didn't have a bf" indicating that I'm not interested in friend zone but in the sex zone. She said they were growing apart indicating she is open to come to my home. Omg, I smelled a chance and I jumped on the opportunity asking her number. I thought I would get her number too but she said I should give her my number and she would call me. We had a little fuss about that and we parted our ways. I hope she calls me to be my "trip sitter" but my experience tells me nothing is going to happen. As I said she works in a smart shop so I can visit her again. In the last part of the conversation I think I ruined my chance. When I asked her number she was very reluctant to say yes, so I picked up my phone out of my pocket and there were couple of moments of silence, I saw her being very fidgety in the corner of my eyes looking for pen and paper. I think it was the silence that ruined the deal? Is it ok to have silences when exchanging numbers? Well, I gave her my number but she didn't give me her number. This happens to me a lot and I was kind of insulted. What should I do when a girl does this to me again?
