Who's he kidding? We've all got regrets. 'Too few to mention' ? Chances are you're so senile you can't remember all the stupid things you've done in your life, or all the bad decisions you've made. The only thing worth really regretting is having no regrets.
Anyway, the time will come when you get your chance to get even. Arrange for all your assets to be turned into cash. Then arrange for the cash to line your coffin. Then specify cremation. But keep it all a secret until that moment when the coffin slides serenely through those little curtains. Who said you couldn't take it with you? You did it - your way!
