When you make a mistake, you say sorry. Isn’t that pretty straightforward? For most people it isn’t. People often make apologizing an ego issue. Almost like, their stature would reduce by saying sorry for a thing they did wrong.
It’s quite the opposite I’d say. If you are thoughtful enough to recognize your mistake, courageous enough to accept that as a mistake and sensible enough to go and say sorry then you’re doing the right thing. Doing the right thing only commands respect. While if you don’t apologize, then probably your stature is in danger
If saying sorry is too hard for you, you’ve an unnecessarily inflated sense of self that won’t serve you well anywhere.
It’s human to err, it’s even more human to say sorry. Don’t overthink it.
