Following your own advice...

You ever do something really stupid and wish you could turn back the clock? (I know we all have).
Well you can't go back but you can learn from you mistakes and not make them again and hope the people you care about can forgive your stupidity.
When people tell me about stuff like this and ask me what to do I usually tell them to suck it up admit when they're wrong and deal with the consequences. The advice is much easier to give than it is to take even from yourself.

I think this little piece of "Monkey Wisdom" is appropriate here:

" Better to be thought a fool, than to open your mouth and prove it."
