Bash him or not???

For me this is a really bugging issue.......so i seek the help of the forum.

Had I been how I was when I was younger, then I wouldn't ask what to do !

However, there is this young guy in my area where I am from. Since he started hanging around local drug dealers.....he has started getting an attitude........real bad .......not only to me but many elder men !!!!! When he was younger he treated people with respect, but for some reason he has become mouthy of late. He has gained a reputation around my area as being a "joker" and that is putting it mildly. The issue for me is that the other day, he started giving the eye ball for no reason whatsoever........................................and this has really infuriated me.........

I am seriously contemplating "filling him in" but then I don't wish to risk getting a criminal record for such a "joker"....................At the same time my patience may not prove too strong !!!!!
