I got nothin' here...

So I just found out last night, as I spent over an hour cleaning a moldy fridge, that my roommate has decided that smoking is pretty cool or whatever. I am not really sure what triggered it in the first place besides the new group of people she started hanging out with, you know the crowd your parents always warned you about? But beyond that, I also found out that she is blaming me for the smoking habit. She seems to think that I am so stressful in her life that she needed something to calm her down. The funny thing is, I never see her, I spend maybe ten minutes of an average day with her.
Now you tell me how I am to blame for her new habit?
I must say, hearing someone blame you for something that could kill them is probably one of the most devastating things you could ever hear in your life.
All I can say right now is try to be a light in a smokers life because you never know when it might turn around and hurt someone totally innocent.
My other roommates boyfriend just told us that his mom has lung cancer that spread to her brain and she has never once smoked. Go figure.
Just be careful with the things you do and the choices that you make, because the things that you say and do could destroy someone else in the long run.
