This happened years ago, but I don't remember writing about it here before, so here goes...
LittleGirl, then 8, had major meltdowns. I mean truly epic, lying on the floor, kicking and screaming, frothing at the mouth style. One really major one was when I insisted she bring a jacket to school one winter day. I didn't care if she wore it, carried it, or stuffed it in her backpack, but as a foster parent, I was under some scrutiny, and I couldn't send her to school without a coat. She went to war over this one with the biggest meltdown I have ever seen. And I have seen some dillies! I honestly don't remember how that one was resolved.
But a week or 2 later,she had just taken a bath, and I went into the bathroom, and found her clothes and towels all over the room. I called her back in, and asked her to clean up. She said, "That isn't mine". I argued (dumb, I confess), "Of course this is yours; there are no other size 8 girls in this family". I could see her face start to darken, tantrum soon to follow, and I said, not my most stellar parenting moment, "This is the most stupid thing I have ever heard of to have a meltdown over". She replied, "Oh, no, the coat thing was much stupider!"
We both ended up hugging and laughing.
I figured only the families who have lived through major meltdowns would understand how funny this is.
