i hate when people say that too!
everything doesnt happen for a reason... sometimes rap just happens!
people say that because they dont understand what you (we) are going through. and i dont think they can be blamed for that - people dont understand because either nothing like this has happened to them, or because it has but they have just been better equipped to deal with it.
i believe in the luck of the draw. it sucks that a lot of us get all the bad luck. (but i tend to be thankful that we dont all get it evenly because there are important little people in my life who i would not want to see suffer.)
