A while back, a child of one of my neighbors was exchanging punches with another one around the four square court in front of my house. I intervened to stop this. The other child stopped, and started to walk away. This one didn't and starting following to complete what had been started. As he was about to engage again, I picked him up and carried him to his house with the intention of engaging in a conversation there. Instead, I got an earful from an angry mother about how I shouldn't be interfering in the affairs of children, and that I should let them work it out. So I've stayed clear.
Some time later, this family was visiting a nearby community. While there, their two year old wandered off and fell in a pool. That child was found unconscious some time later, and has been in the hospital since.
