If an apology is followed by an excuse or a reason, it means they are going to commit same mistake again they just apologized for.

Mistakes made me matchless.

In the mirror, if you don't see a man without mistakes, then expect and accept mistakes from others.

In the matters of your mistake you defend it like a lawyer, in the matters of other's mistake you act like a judge.

People regret uncovering of their sins more than their part in the sins.

The mistakes of the world are warning message for you.
