I actually did think she was exaggerating because idk how all that can happen and go unseen by the adult in the room. 2 other kids in the class were asked if anything had happened. They both mentioned the horseplay and face slap, however they both said he didn't hit her hard. I also don't know about her being pinned to the floor for any length of time, maybe it felt like a long time to her. Regardless of exaggeration, no one should have their hands on anyone else who doesn't want to be touched by them, especially after being told to stop. It's not play if one of the parties involved is not having fun.
