There are probably thousands of examples that people could come up with here. One story I like to tell is about my friend and his wife. They have one son who is 11 yrs old. Anyway, we got together on a weekend several months ago. We decided to go bowling on a Saturday. So we get to the bowling alley. My friend is not a smoker, his wife is. He asks if she wants to bowl? She says "No, I think I'll just go and get everyone some food." So we start to bowl, she comes back about 20 minutes later, with some nachos. It didn't take 20 minutes to get the nachos, my friend and I saw her go outside to smoke, so did her son, unfortunately. So we keep bowling, and eat some nachos, and in the course of the next hour or so we see her go outside another two or three times. I had been quit for a while when this happened, and so it was very clear to me exactly what was going on. I think we saw her for about 15 or 20 minutes in an hour and a half.
Was she doing what she wanted to do? I think she wanted to spend time with her husband and her son, but the addiction controls people. Don't let it control you. Quit, and live the life you want to live!
