My dad said he smoked when he was young, but he quit long before I ever came along. Smoking was rarely a subject in my house, but when it was, it wasn't discussed in a positive light.
I remember back when people were still allowed to smoke in a mall near my house. I remember hearing other people complaining about the smell, but I always really liked it. I started smoking in college, during a summer away in another state. Me and a new friend of mine there went on a little weekend road trip and decided we were going to smoke while doing it.
I dunno... I guess being in a new place with new people for the first time in my adult life left me in the mood to try new things.
