Just a thought I had, like what can a ten year old do(besides mass murder & accidents) that messes up their life so badly that it is unrecoverable?
It has to be something that is self inflicted and not something that is the cause of others around them.
I remember as a kid, I met these other kids that would drink from the side of the street. That sewer water was full of nasty including gas and oil runoff from the roads and who knows what else.
I also had an ex that would drink the chemicals under the sink as a tiny kid.
