Person1: It smells like an ashtray in here !
Person2:Hi honey ! What ' s wrong ? Why do you have that look on your face ?
Person1: What ' s wrong ? I thought we agreed that you were gonna quit smoking .
Person2:No ! I said I was going to cut down which is very different . You can ' t just expect me to go cold turkey overnight !
Person1: Look , there are other ways to quit . You can try the nicotine patch , or nicotine chewing gum . We spend a fortune on cigarettes every month and now laws are cracking down and not allowing smoking in any public place . It ' s not like you can just light up like before .
Person2:I know , I know . I am trying but , I don ' t have the willpower to just quit . I can ' t fight with the urge to reach for my pack of smokes in the morning with coffee or after lunch ! Please understand ?
