Thanks for your input, everyone. My main gripe is that this was not only traumatic but unnecessary.
I was handling it. I know the sozlet well, I know how she operates, I know that if I step back and let the pluses and minuses of the situation become obvious without forcing the issue, she will come around. She was a minute or so away from saying, OK, this is boring, I'm up here in Mama's arms while they're all playing, lemme down.
As Noddy says, I was in the midst of getting outta there, was hung up by procedures. Had no objection to getting out of there, per se, have done that the last several classes (this one) and last dozen or so classes (previous two) with no problem. She hasn't been upset, ever. This took a lot of talking, a lot of role playing, a lot of positive reinforcement afterwards, but not upset, once.
The hanging around and watching was through a window, looking at the reflection in the mirrored wall, she didn't know I was still there.
Anyway, here's what happened:
I showed up early, looked through the window (again, unobserved), she was fine. When the doors opened, I was very careful not to show any concern, was bright-eyed and bushy-tailed and "Wow, I saw you doing the Hokey-Pokey! Were you wiggling your tummy?" Right into positive things about the class. She was a little clingy, but smiley and answering my questions. Then she wandered off to talk to her friend and her friend's little sister, and I cornered the teacher, who did not want to be cornered. I said, together with a look that said "if we were not in a room full of kids I would be putting this
much more strongly," "I would prefer that you not handle that situation in that manner in the future." She started to say the parents should leave right away, etc., I said "Yes, I understand that, and was attempting to do so. I did not appreciate your interference, nor the manner in which you interefered." She got a little huffy, a kid came up to ask her something, I gave her one last look and then went back to sozlet.
Sozlet and I went to lunch and talked about what happened, gradually. I didn't lead with it, we talked about other things, then she said that Bridget helped dry her tears. I said oh, that was so nice of Bridget. She's a good friend. Then I said, I'm sorry you were so sad, honey. But it looks like you were very brave. She said that yes she was, and I said I hoped she was proud of herself for being so brave. She said she was.
To loop back a bit, I think the deafness thing was an issue here -- the teacher in question is clearly uneasy about communicating with me (lots of over-enunciating, pausing while she chooses the simplest possible words, that sort of thing) and I think that she decided to just act rather than communicating with me about what needed to or was going to happen. If she got my attention, said, "I'm going to take her now," I would have said something like, "OK, sorry we're taking so long, give me a minute" and if that didn't work, I would have talked to the sozlet to ease the transition. Not just this grabbing her out of my goddamn arms crap. That really ****ing infuriates me. ARGH.
At any rate, I think the sozlet is generally secure enough, has enough grounding in the fact that I'm going to take care of her and not let anything too horrible happen, that she will get over this without too much problem. But if it happens again, she's out of there, and it will take a lot of willpower for me to not do bodily harm to the grabberwoman.
I will be proactive and positive about it, though, will do my utmost not to convey this mindset to the sozlet. I believe I will write a note stating some of this (as non-pedantic as I can make it), and with the contact info that we parents usually have to write each time, so I can just drop that off and begone (that's what takes the most time, there is a line.)
Deep breaths.
She really seems to be fine, and was happy enough to talk about the good stuff, so I think this can end up just being a blip.
Thanks for letting me vent, and for your insights.
And Craven, how sad for you and your siblings.
