I was abused by my father for 15, 16 years. My brother's taken over now - it's not as bad as it could be, though.
I don't tolerate drugs, alcohol, tobacco, anything. Not in my house, not on your clothes, nothing. I can't handle it. My dad smokes, drinks, does pot (my sister thinks so, anyways). No way in hell am I voluntarily having that stuff in my future.
Just my opinion.
