So get over it.
That’s a problem. Sooner or later you’re going to have to own up to that and ask again. For now call her Cool Biker Chick.
Who cares? Assume she doesn’t. If she brings it up later, then you’ll know. And please please please, don’t ask. That’s an instance where a false positive can ruin things for both of you.
But I get it about blowing in-the-moment chances. I had one yesterday.
I was stopped on the sidewalk by two incredibly cute young ladies. They wanted to know if I knew when the parking meters were no longer in effect. I said that I think it’s 6:00, but it probably says right on the meter. We searched around and found that yes, it was in fact 6:00. “Huh, five minutes to go”, one girl said. “Do you think we’ll be OK?” She was asking me as much as she was asking her friend. I was clearly in an interaction. I said “Hey, if you want to take the chance… Just put in a quarter, you’ll be good.” She said she didn’t have one. Her friend started looking for nickels and dimes. I rolled my eyes and handed the friend a quarter. They were greatful. They were incredibly greatful. One immediately stuck her hand out to shake mine and called me a great guy. Their body language screamed that I could have asked them for anything, and they would have gladly given it. I used that tried and true pickup line “Ok. Umm… bye.”
Jackass.
