He is just a kid. I think we should just ignore it and move on. No need to put his pictures up and shaming him any more than he did himself I think.
Pulling stupid crap is part of being a 15 year old. Yes, it is frustrating, ask any parent or teacher. But at the end of the day, you just hope their mom gives them a good spanking every now and again and move on. Can not say he is too young to be held accountable for his actions. But kids and the internet... what are you gonna do?
When I was 15 I worked at the market 7AM to 18PM on saturdays, at the local grocerystore on tuesday, thursday and friday afternoon, and I could barely afford a PC... let alone a 200 dollar keyboard (don't even have one now). Can not lie, kinda jelly.
