Frame tests always happen between friends and strangers.
The frame of the event is is whatever you want it to be.
You approached, she tested, you left.
However, I would recommending using what she said to practice for next time.
Instead of just having an open ended frame of having fun, pre-frame by expecting a little bit of resistance.
Pre frames are much better the outframing after the fact, at least in social situations.
Every situation is a tool to learn how to do better in the next situation.
There is never any wrong or write answer, it's always about the continuous increase in skills.
