There's No Fool like an Old Fool
( a foolish act seems even more foolish when performed by an older person, who should have a lot of wisdom)
Did you hear about Henry? He's gotten married again.
I can't believe it! At his age? This is his third time, isn't it?
Yeah. There's no fool like an old fool. You'd think he would have learned when his first two marriage ended in disaster. I honestly don't see how this one can last,either.
What makes you think that?
Henry's job. It requires long hours and keeps him away from home six months out of the year.
It seems that ol' Henry hasn't learned anything from his previous relationships. He's already got two strikes against him - his age and his job. And there's nothing more ridiculous than the foolish behavior of a person who should have learned something from his previous experiences.
