I have found that it is usually better for me to say nothing at the beginning, at the moment I feel like saying something. At that moment, it is usually best not to say anything because if I say something the very moment I feel like saying it, the juice is not sweet. It’s sour. And no matter how true or right what I have to say is, all the hearer notices is the sour, bitter, angry or judgemental note hidden in my words.
