Yeah it’s a constant balance but aggression is needed. This idea that the world is calm and we all must get along isn’t true. The universe is chaos and boundaries have to be set. Just like we have to find that fine line of privacy and security the same has to go with aggression and passivity. Need that balance. I rather your son crumble after getting hollering from dad than from some random stranger. At least you are there to show him how to manage such situations in life. Even when they come from you.
