It is better to leave something unsaid! Yesterday, two of my friends came to my school and invited me to have a lunch with them. on the way to canteen, one of them laughed at me that the coat on me is out-of-date, which is my dad bought for me. And he also said that he always thinks that I leave my hear unwashed for several days, but actually I wash my hair once a day. And he also make a joke of the color of my skin. I got mad yesterday.I think it is impolite to discuss someone in a public occasion, even if we are friends. He really embarrassed me and hurt my feeling yesterday! What's more, I think it would be better to leave something unsaid, especially the discussion of ones appearance.
