Never ruin an apology with an excuse.

I can’t apologize for who I am any more. Even better, I have no desire to.

It was never my intention to cause you pain. Whether you feel strongly or very little, that does not excuse thoughtless behavior." - Adam

Apology makes you self responsible while excuse makes you undependable

Never apologize for showing your feelings. When you do, you are apologizing for the truth.

By the time most people say 'I'm sorry' it is already too late.
