Thread: adult friend screaming at my son, is it OK ?

two boys playing water-fight child A tips 2 litters of water over the child B head after child B tells child A that he does not want to be wet (witch he dose allot only to turn around and wet child A) Child B's mother comes out just in time to see Child B's drenching and go in to overboard mode screams on curb for full 2-3 minuets at my son child A.
As quickly as posable I pull child A and B away from both of us And I remain calm to discuss said behavior Parent B rants at me for quite a while coming to the conclusion that my son and i were ganging up on her son. she did accept that she should not of screamed at child A the way she did and asked to apologies and it went well for the first 4 words and then there was a but and she continued to berate my son on his infraction of witch I had ashore her that I would deal with it
now I am faced with the dilemma, do I to stay her friend even thou I don't believe in her "respect my child NO even if he uses it to annoy the shit out of you and your son " and I don't believe in "sorry BUT" and this is not the first time she has behaved in this way i will quote now "you stay so calm Parent A it is spiteful"

I liked having her as a friend but i don't think yelling like that is cool at all

they were in a water fight
