Stupid fuckin question, it’s called addiction. I started before he ever had cancer, he smoked and his dad died of a heart attack because of smoking. it’s not like he was diagnosed and I was like “fuck yeah, let’s go smoke cigarettes!” Dumb ass, it’s a huge picture and only people who have faced these problems know what it’s like. That’s like asking “how could you still eat even there are kids in Africa starving” or asking somebody who’s depressed “how could you want to die? There’s so much to live for” when you have a perfect home life and do well in school. if you don’t know me or anybody in my family ESPECIALLY my dad. Then please fuck off. Thank you kindly.
