I like to consider myself a Stand Up Guy if in the Heat of the Moment I do something Stupid and later I realise that I made a Mistake I would gracefully ask for an Apology without a second thought.

Accepting your Own Mistakes and Correcting them is a Way of Life. It's better to Correct your Mistakes rather than Ignore them. Believe it or not one day or the Other your Mistakes will come to haunt you.
