My nephew always seems to get into trouble that could be avoided, and I'm really concerned. I think I'm going to comment on it.
Why do you think the issues were preventable?
I feel the child is acting very violent for no reason at all.
Honestly I think it's their parents responsibility for their child. But I understand your concern and I salute you for caring about this child, and I would recommend you contact their parents first so that if they can discipline this child or if they can do something about it.
They really need to take responsibility for this kid, Hes a terror and something has to be done.
I agree with you there, the parents need to be made aware and take care of the problem. I highly recommend you communicate this with them so they could start talking to the child.
