LYRICS

[From October 31, 2002 version]

Do you realize you have the most beautiful face??
Do you realize we're floating in space??
Do you realize that happiness makes you cry??
Do you realize that everyone you know someday will die??
And instead of saying all of your goodbyes
Make them realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning around
