My dad used to intimidate me because he “didn’t have time” to wait and wanted me to “spit it out”. I think it just led to me speaking to him less. In hindsight, I wish I had told him how it makes me feel when he says things like that to me. I would catch this person in a one on one and express your feelings to them so you don’t end up ostracizing them from your life. Finishing your sentences takes away the ability for you to have creative or original thought.
