Ask a smoker why they continue to smoke even if they know it could give them cancer.
Ask an alcoholic why they continue to drink even if they know that it could destroy their liver.
Ask her why she's chasing him even though she knows he's only going to cause the worst heartbreak and probably destroy her.
Ask him why he's still popping his veins on some drug even if he knows that everything around him is dying and he's soon to be next.
Ask him why he's cutting himself even though he's only breaking himself inside out and creating scars that will haunt him.
Maybe they'll give you an answer that I cannot give you.
I could say I'm doing it for the thrill but the reality is it's an addiction that I cannot fathom.
