"I've been using crack since I was 18, and I'm 27 now. I mean, that's almost 7 years I've been doing this stuff. I've spent 2 years in jail for it. I've been in and out of every rehab program in town. I've never had a real job, and still live with my parents. It's time for me to turn my life around, and I'm going to start by being honest and telling my parents about my habit. I've been able to hide it from them, but It's time they know I've got a problem."
Dude, if your parents haven't figured that out yet, they're probably on it, too. Also, your math sucks.
