I was at the play space upstairs at the Tyson's Corner Center shopping center in VA today. Wednesday, May 19 at about 2:30.
I watched a (what I assumed were) brother and sister pair pummel each other, and later pummel other children. They punched, kicked and grabbed each other and looked around to figure out who they were there with. I eventually figured out that they were brought by a nanny. The woman, who seemed to be a Hispanic woman in her 30's (wearing a white, zip-front hoodie), spent the time on her cell phone. She wasn't even speaking to anyone - she was texting or reading. She was completely unresponsive to what her charges were doing.
The girl was about five years old and her younger brother was about three or four. I tried to stop the girl from pouring water all over the climbing structure. An unrelated four year old told her that the boy was being very mean.
I'm not talking about gentle wrestling, there was biting, scratching and full body tackles. It was horrible. Other moms came over to scream at the children. My sister and I took our children and left. It was horrible to watch.
