How to deal with someone who never admits they're wrong?

is your dad a leo? just askin im the same way really but maybe he has a problem with the word , or he was hugged enough as a child ,or his parents were always right so hes the same way, my mom is the same way i dont think i have ever heard her say im sorryi really dont say it either,unless in my heart i feel it ,but alot of things happened to me when i was younger i dont know if that stems from that or not , but the door thing , maybe he just has alot on his mind and stressed out becouse he said alot to you that had th do with the door thing,he dosnt has no compion am i correct. just go to him and say dad sorry isnt a bad word its a good word to use when ur at fault but it wasnt done intentionaly ,just to let the other person know that you recognized the situation and sorry,then everyone feels better. love you dad
