I think the right answers to those would've been to assure the bullied person that they play/look fine, offer a bit of praise about them (you play fine, wish I could stay that in synch & I couldn't pull off that look) and then ask her why she has to be so mean to people. Of course, she'll say something mean to you, but just let it go.
I understand that she is asking for it by being rude, but it isn't worth it. My brother and sister-in-law are no different, they thrive off of high school drama and try to get everyone they can involved in their stupid games. It has lead to them outing me to around town when I don't take their sides in petty squabbling. I let it go. I don't speak to them nor do I consider them family, but I don't perpetuate their drama. And of course people talk and say nasty things, that's what people do. However, a lot of people see them for what they are the minute they (other people) tell me what's being said and hear me say "I know what they're saying, I'm not going to let it get to me" and leave it at that.
Finally, and I'm not trying to beat a dead horse, but the fact you brought up such a story in this thread implies that you took pride in what transpired. That's really what I think is most concerning to us.
