We were sitting at the baby pool during “break”. I saw this young lady about 10 years old shove her younger brother into the wading pool. He fell backwards, and when he got up you could tell he was upset and then started to cry. She then proceeded to grap him by his life jacket and drag him out of the pool, once she did that she started dragging him towards a picnic table behind me. When I turned around I saw her slapping him in the head, and he was protesting and you could tell he was upset. I had to speak up. I told her she needed to stop what she was doing and that it wasn’t acceptable behavior. SHe told me “He’s my brother!” and I told her that I really didn’t care who he was to her, that it was not acceptable behavior no matter what. She just glared at me. All this time I was wondering where the parent(s) was/were. After break I took my kids back to the pool where I saw the mom on her cell phone. Would you have done the same?
