No, this is not about the BC19 cooldown.
It's about how hard for some people to say sorry even after knowing they've done something wrong. The bigger the EGO, the harder it seems for the mouth to utter those so-called "humialiating" 3 words.
I too have that problem sometimes, but I'm making effort on that.
If we really think about it, saying sorry is never about losing face. It actually takes a real man(or woman) to take responsibility for the mistake/error made. If anyone sincerely realises his/her wrong and apologize to me, I would not think less of him/her as a person. Instead, the person will probably earn a new level of respect from me.
Unfortunately, some people may never understand this.
