1. I don’t care
There are times when you might be upset or angry with someone, and the only thing you want to do is to scream at them and say that you don’t care about what they do or want. There is no need to do that, especially when you will feel extremely sorry a few moments later.
When you say that, what they hear is “Please don’t bother me. I’ve got more important things to do than listen to you!”. Instead of having a harsh attitude, you can simply tell them that you are curious about their story but now is not a good time.
