Yes she can also decide to get an attorney and sue op for defamation of character (just taking it to an extreme) Remember folks the daughter can easily say, "I never said any thing at all". Why should ER mom believe some random 16, 17 year old over any other. Folks lets remember op did not directly hear this. she is getting this 2nd, 3rd possible 4th hand. Her son told her, not to say he is lying but he too might be ramping this up, after all he is not totally unemotionally involved. On top of that he has said he really does not talk to this girl. How is he going to prove to ER mom that her daughter is spreading a rumor? Everyone here is automatically assuming that this "girl" definitely said what supposedly she said. with absolutely no proof. Call me crazy but if you come to me accusing my son of starting a rumor you'd better have some thing more than, "well sally said, that john said that billy told him".... which is all op has.
