I went to a yoga class today, and this hot girl puts her mat down next to me. I'm thinkin, ok, that's probably an ioi, especially considering there were many other spots she could have chosen. So I wait for her to give me another ioi, eye contact, something. Instead, she just spends the entire time playing on her phone, doing pre-class stretches, etc, and doesn't once look in my direction or in any way indicate she's interested.
It was a great class, and afterwards I turned to her with a big smile and exclaimed, "that was great, no?" She replied with a nice smile, "ya." I said, "you have a really nice practice," she was good and has obviously practiced for years. She smiled again and said "thank you," and abruptly walked away.
Now, I assumed she wasn't interested, because if she were she would have given me an opportunity to extend the conversation. As such, I didn't bother trying any further. But perhaps she was just giving me a shit-test, to see if I'd persist and keep going for it. Opinions? Next time, should I just keep going? Or were my initial intuitions right, in which case I would have wasted my time had I chased her?
