Sure do. I usually apologize because it prevents tension and it isn't that big a deal to apologize for something. If it sully's my character, ethics or reputation, then I'll stick by it for the most part. Sometimes I'm resentful because words were taken out of context, taken offense at, tone exaggerated, etc., but if someone took it wrong and absolutely needs it to move on, then who am I do really refuse to apologize for actual words spoken, regardless of intent.

I would, however, appreciate the benefit of the doubt until I'm able to defend myself either way and discuss whether an apology is needed or wanted, not demanded.
