Nobody. I've been that person. Definitely. I'm not sure about this specific thing; I'm pretty laid-back when it comes to accepting apologies. It's like, whatever. I can't even really remember the last time I felt wronged enough to warrant an apology.
But with my actions in general? Most certainly. I have lots of regrets about the way I have treated people.
Like I said to you over on my post, we all try our best and we all sometimes fail. But the opportunity to talk about it is always helpful, so thanks for the open ended question.
