Today, inspired by a toot in my timeline, I adopt the supposition that if everyone is my teacher, then to everybody else I must be a teacher as well. I adjusted my comment composition with that in mind, going from Premise A to Conclusion in a straight line without missing switches or derailing and it's a positive, self-affirming feeling. I don't even need the ego gratification, the warm fuzzy of having a conversation without whataboutism, logical fallacies and name-calling is satisfying.
