I think it's more of a "which one is worse" kind of scenario.
My sister is worse than me. She shoots heroin still, drinks every day, pops pills, does whatever drug is given to her, doesn't have a job, prostitutes for cash when she needs it, and dropped out of school at 16. I however just drink and dabble in coke, am kind of a bitch all the time, unemployed, don't prostitute, and I go to school full time. Ironically, we both have herpes.
