Well gee, that Mom is real childish isn't she? Sticking her tongue out....
I would, talk to the Husband, or the Mom... if she is even willing to talk to you. She seems really against any socializing at all.... now.
So why were the kids 'fighting' all the time, anyway?
My kids with their friends, don't fight.
Maybe your kids and hers, just don't get along.
Which is fine. Not all kids have to get along or be friends.
Your kids were at HER house for playing?? And that is where they were fighting? Well, it is her house... and if she can't handle the so called "fighting" as she calls it, then well... she is doing what she thinks is right.
BUT she could have... TALKED to you about it first. To see what could be remedied....
Regardless... that Mom is really infantile. And to act that way.
If anything, just explain to YOUR kids... that not all adults are "appropriate" and not all kids are either. AND... that sometimes, it is better if 'we' are not friends all the time, with the same people. It can be very negative and unfair.... and their Mom is not the kind of parent that you want your kids to be around....
Frankly, I would be glad that I know this about the Mom. Now. I would not want my kids, around her nor playing with her kids.
Who knows, what exactly went on with the fighting at that Mom's house. Did you ASK your kids, what was going on and why ALL the fighting???
Regardless.... I would now not want my kids around a parent like that.
IF that Mom... continues to mock and harass your kids, at their Library... I would tell her Supervisor. That is REALLY out of line.
all the best,
Susan
