Are things still going badly with your houseguest ? Getting worse . Now he ' s eating me out of house and home . I ' Ve tried talking to him but it all goes in one ear and out the other . He makes himself at home , which is fine . But what really gets me is that yesterday he walked into the living room in the raw and I had company over ! That was the last straw . Leo , I really think you ' re beating around the bush with this guy . I know he used to be your best friend in college , but I really think it ' s time to lay down the law . You ' re right . Everything is probably going to come to a head tonight . I ' ll keep you informed .

Now, solve this instance: I'm looking for some black pumps to go with my evening gown . Could you show me what you have ? Sure , we have several different styles you may choose . How high of a heel do you want ? Not to high , maybe an inch or an inch in the half would be the best . In that case , I might have just the pair for you . Look at these , they were made in Italy , the leather is very soft , so your toes will not get pinched . You can tell just by looking at it that it was superbly made . Those are beautiful . Do you have any in a size six ? Yes , we do , we also have this same style in dark blue and red . No , thank you . I'm just looking for a black pair . Let me go to the back and get them . I'll be right back .
