Did you hear about Joe ? She hasn't eaten for days .   Why ? What's eating her ?   Love sick . You know who she's in love with ?   I don't have the slightest idea .   Someone you're living with .   What ? Not my Dad , I hope ! ?   Come on , Mary , it's your brother , Jack .   No kidding ! Jack is such a log ! He's never dated a girl .   The problem with Joe is that she's too shy to tell him .   And the problem with Jack is that he seems to have no interest in girls . He's putting his heart into his stamp collection .   Well , if you want to help your friend , you should do something about it .
