It's really his fault to spit. It should be said that it is too much, but no one is perfect. Maybe it's just a microcosm of your father's personality defects. I don't hate him. I just think he should apologize to you. Maybe you just can't get over it. Your father isn't. Think about it. If he says his son is sorry for you, do you think you can overcome this psychological obstacle? Think about his efforts. Will you forgive him? You will get the answer yourself. I believe you still love your father.
