I read a post about maintaining frame a few moments ago and I started wondering if this thing I did is considered breaking frame.

Basically an acquiantance of me and this girl asked me a question I did not want to answer and I made a serious face, she said "I guess I shouldn't have asked this" and then put on a wide smile.

To me, this was a joke.

I'm asking since it wouldn't be the first time I did something like this so I want to know if I should control myself.
