 Person2:  Honey , we're in the museum now . We're not here to discuss your coworker's love life . We're here to enjoy the great paintings by Picasso ! 
 Person1:      I know ! But it's really important to her ! Her whole life could be ruined by this man !

 Person1:      Are you serious , John ? 
 Person2:  All I'm trying to say is that life is ... like ... er ... this painting .
