Regrets, I've had a few. But then again, too few to mention. Yes, we're starting with the late, great Frank Sinatra. And if you don't know who that is...well, now I feel old.
Anywho, although Frank wasn't one to dwell on his mistakes, I'm going to guess the next 16 people — and a couple animals — can't say the same.
Come revel in their failures. You'll regret it if you don't.
