So I met this girl at a festival, we talked for a while, had some fun.
When I had to leave she said, if I wanted to contact/know more about her, I had to talk to her older sister (attends the same school as me/worked together for a while). Assuming that she said this, I didn't ask for a phonenumber or what so ever.
So my question is:
should I give it a try or is this some form of rejection, assuming she did not give me any phonenumber?
If not:
what is the best way to approach tis older sister of her, what should I ask?
