This woman I used to work with was all bent out of shape because she heard two other employees criticizing her. She was eavesdropping on them, and they weren't aware that she could hear. I reminded her that many times she had spoken harshly about others, and if they heard what she said, they would feel badly too. Everybody wants to be liked I think, but it's realistic to know that not everyone will be fond of you or your opinions. If it's someone close to me, I'd care more about what they thought.
