Give me a cigar? Please... that's tobacco.
Go ahead and smoke. It's not a matter of my being self-righteous. Just view that kind of dependent behavior as being pointless. I'll take the bananas any day. The funny thing about smokers is they usually agree that they need to quit... right up to the point where it looks to them like they're being criticized for their behavior. Once that happens they get defensive and tell others to back off, they can do what they want. Seems like a life of conflict, but that is the nature of addiction whether it's tobacco or alcohol or heroin.
I honestly don't think I have any vices. I don't do anything or use any substance (not even a food) in an excessive manner.
