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 .
Person1: 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 .
Person2: You ' re right . Everything is probably going to come to a head tonight . I ' ll keep you informed .
