I wouldn't say you are deciding how to feel.My generation was brought up on "Sticks and stones may break your bones but words can never hurt you." I had a fairly well known psychiatrist essentially tell me the same thing. "Nobody can make you feel anything with their words. If you are feeling something it is because you are choosing to feel something. You are deciding how you want to feel. You always have the ultimate control. To be constantly at the mercy of people's careless verbalizations is a sign of instability."
I would love to run into him again and see what he thinks of all this.
It's more like you are deciding how to interpret your feelings.
