My friend is being rude, what should I do?

Looks to me ur irritation with lily was the reason for u to stand up for sally, anyway does sally need someone to voice her tots? I hope not.. in such instance wat u did come across as rude & not lily, since she was voicing her opinion to sally & not u. as for talking to her depends on whether u value her friendship – since u painted her as an opinionated person the question is whether u wan such a fren? Answer that & u will know whether u shld to talk to her or not.
