We stumbled onto a topic about her breasts. I commented that her breasts were pretty big back in Grade 6, which were a C cup. Then she said that she is an E cup now, then I jokingly said that I want to grab her breasts. Out of the blue, she told me that I can go for it, which made me thought she was trolling. I, being a person that outsmarts trolls, said that she and I should meet up in a month and then I will grab her breasts, she said maybe. Now, I just facepalmed at my actions because it was idiotic of me to suggest that she and I meet up to do something so indecent.
I do not know how to deal with a situation like that.
