I have noticed that when someone starts out by saying, "I don't mean to be a jerk, but . . ." or "Don't take this the wrong way, but . . ." what they then say after that is often hurtful. However, if another person gives me the exact same feedback without the introductory disclaimer, I don't feel put down. I wonder why this is.
Recently two different people, separately, gave me the same feedback. One was a straightforward suggestion, which was very welcome The other made the exact same suggestion, but couched it in no less then three apologies (such as "I don't mean to be a jerk, but you should . . .) for making the suggestion.
