When you reach your 50's , I'd naturally assume that all that sort of thug mentality - and blaring your car stereo for all to enjoy - would be out of the blood.
Now wait a cotton-pickin' minute...
I'm 56, and I like playing music pretty damn loud sometimes... I've got a 2000-watt PA system for my band and when I crank that sucker up it can knock any car stereo into next week.
That said, I play rock and blues and jazz, not ghetto-crap. IF the 55-yr old was playing loud [c]rap, I'd probably think about shooting him too.
"Geezer" my @$$.... ;-)
