Turns out, it was two friends who were playing and wouldn't let her play with them. I hear a lot of this. There's one girl in particular who, if she is playing with someone, no one else can. I kept hearing this over and over so many times that I finally talked with M's teacher about it. Only to find out that she wasn't the only one this girl was doing this to.
I have discovered that it is my karmic payback to have a mini-me who feels just as rejected as I did when friends didn't want to play with her. Except that all I see is a beautiful, sweet girl who I can't imagine anyone not wanting to play with.
I tried to talk with her about just finding someone else to play with and that sometimes it's okay if they have enough people for their game. Then my drama queen explained that everyone always has enough people for their game.
I know she's a drama queen. I know she exaggerates. She's a mini-me, remember? I just am not that good at helping her reconcile her rejection yet.
