I wanted to approach someone and I felt it wasn’t the right moment

I wanted to approach a girl on the table next to me, I thought she looked super cool and I didn’t. I wasn’t alone and I didn’t feel there was a right moment to approach to talk to her. I was with someone and so was she. I was walking out and then I decided to turn around because I knew I wouldn’t see her again. But when I went to look for her at the place I looked but she must’ve left. I wouldn’t approach a stranger if I was like minding my business I just felt we could’ve been homies.
