This is one of my all time favorites....
You can choose to live your life with unbridled joy and good humor like the occupants of the first car or the solemn rigidity of those in the third. It's up to you, but my advice would be to throw your hands in the air, scream for all you're worth and know that you are fully alive as you begin the downward plunge. Life is too short. Enjoy the ride!
Boy, doesn't that say it all? I am sure we all know people that we would just love to toss in the front seat, just to see if it will shake that stick out of them...heh,heh...I know I do!!!
