Congrats on becoming a granddad.
Don't worry about your granddaughter, she'll turn out to be a strong, young lady with character.
Take it from me, a Chicagoan. Plenty of trashy, hood families here, including my own. Me and all my friends and every kid in the school grew up around alcoholics, junkies, livin' from paycheck to paycheck. And every one of us sorry ass motherfuckers turned out hard-working and responsible.
I'm assuming your family ain't that bad, but point is, shitty families make good people.
