If you're someone imperfect like me, chances are there were times when that's exactly what you wanted -- TO HIT UNDO. Sadly, some things just can't go back to how they were. You have to deal with the mistake while hoping for your luck to turn around. And to carry on, even if lady luck fails you. Oh well . . . . . that's life!

So toughen up, buttercup.
