That's a tough one, I do that a lot as well. I think it's because I had very demanding parents with bad tempers. Apologizing was definitely a defensive thing, growing up. If my parents were off on a tear or in a bad mood, I wouldn't get the support and care I needed. Anytime someone is angry or upset, I tend to apologize even if it has nothing to do with me because that's my go-to for regaining peace in the atmosphere...I've gotten better about it at work but still do it a lot with my mother.

I think a lot of people deal with the same issue. It might also be a self esteem or confidence thing? I have really bad self esteem.

Good luck with your homework! Hope you get something positive from it!
