Long story short, once upon a time I found myself involved with a lady who happened to have a husband.
One day while I was out with some of my friends, I received a call from her and I instead offered if she would like to hang with us.
She agreed, and when the night was coming to a close I asked my friends what do they think about her, noting that she is someone who likes to have fun.

I guess I misread the situation and her intent for being there, because she pulled me aside and started with "what the fuck is that supposed to mean?" and that "that's (fun) not what this is for me".
After that outburst she left, noting that she doesn't want for us to meet anymore.

Boy, was I confused.
