Did you ever have to say “no” to somebody? Such as a classmate who asks to go to lunch with you, or a roommate who asks if you would like to continue living together in the future? New research suggests that, at least socially, a rejection should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.
