Dd stayed over at a friends for a slumber party. Dd is 7. when I went to pick her up today I noticed dd wasn't with the other kids at the table eating a snack. When I asked where she was the mom (v) said "oh she ran through the house a while ago so I'm making her do the chair." The chair? Its where dd had to put her back against the wall, bend at her knees like sitting in a chair and hold her arms out with a stack of books on her hands. I flipped the hell out! I understand she shouldn't have been running but really? She could have sat in time out or stood in the corner like a normal child not had to do that. She was crying her eyes out and you could tell she had been there for a while. She will never go back there EVER. My grandmother says I'm over reacting, what do you think? What would you have done?
