What's the matter , Lisa ? You don't look too good .   I just found out that my husband is cheating on me .   You mean Mark ? He seems like such an honest guy .   That's what I thought . It seems that he's been seeing someone else for about two months .   Two months ? How did you find out ?   I asked for leave and was at home when the telephone rang . I picked it up and a girl asked to talk to Mark . She then asked if I was his sister , and I said no , I was his wife . She hung up immediately .   So you asked him about the girl who called ?   Yeah , he first said it was someone from work . He gave me a lame excuse , and so I pressed him on it .   What'd he do ?   He kept trying to make stupid excuses , and then broke down and admitted to a small indiscretion .
