I'm such a meanie NF . I don't apologize much. Occasionally I "over explain" what seems to be a misunderstanding so no one has sore feelings caused by poor communication. However, I'm not someone who says "I'm sorry" a lot. I've actually had family get mad at me for my lack of apologizing. I tend to let time soothe and use actions to show remorse, unless it's something stupid like stepping on your toes (literally), then I may apologize.
