Underhanded Compliments

Recently, I received a compliment from somebody. However, the compliment I noticed was slighty underhanded, in my personal opinion. Not getting too detailed, it compliment referred to a job well done however, there was a smart comment after it that was both uncalled for and justplain unnecessary. I shared this not so compliment with one of my close friends (I made sure to keep the name of the person anonymous). My friend upset. Almost borderline irate. She found it to be inappropriate and hurtful. The question I pose today to everyone is why give someone a compliment when you A: Don't mean it or B: Mean it and feel that you have to add in your digs. There are certain things you do not say to people. You may be thinking it, however, anyone with a common sense would no better not to even utter such words. Somethings are better left unsaid. If you feel that you must make a compliment with a underhanded remark, maybe you should rethink the compliment.
