Oh, so I guess she shut you down, huh? You should've delivered it playfully.
Michelle did her friend a huge favor be telling her the truth.
I have feeling that person simply refused to look honestly in the mirror, even after begin confronted with the truth, and that their lunch conversation was the end of their relationship. Considering the value of one’s limited time on this Earth, I think Michelle, in attempting to help another, also did herself a favor by ridding herself of an unpleasant time-sink.
