I smoke but, even I know how disgusting it is. I really have to quit. I never ever ever ever ever smoke in inside the house though, and never in public areas specially when the area is closed.

About that spitting thing, Our neighbors (from where I used to live) used to be an accomodation for about 40 or so people, every morning they would have this "throat clearing" competition just around the time we're having breakfast. Long story short, I got an ulcer for skipping breakfast all the time.
