Q: 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 ?
Person1: Fine ! I want a divorce !

Q: Person1: Jack and Mary broke up .
Person2:it ' s so sad . They had been together for only two months . Do you know what the matter was ?
Person1: Mary said Jack was cheating on her . Jack was seeing a girl from his hometown . One day , Mary saw them holding hands and ended the relationship immediately .
Person2:really ? I ' m very surprised . He doesn ' t look like a guy who ' d ever do that sort of thing , right ?
Person1: no , he doesn ' t . Anyway , she found out that he had been two-timing her for a long time .
Person2:maybe it is for the best . They are not suitable for each other because they have nothing in common and are completely different people .
Person1: how so ?
Person2:he is an extrovert while she is an introvert . He likes parties while she hates them .
Person1: poor Mary ! She really liked him .
Person2:anyway , she was right to end things and she deserves better .

Person2:no , I don ' t think so . I know Mary . Once she makes a decision , she won ' t change her mind .
