“You are my life, but you are not my purpose.”

Video farewell (2002)
Context: I have lived my whole life on the stage and screen before you. I found purpose and meaning in your response. For an actor that is no greater loss than the loss of his audience. I can part the Red Sea, but I can't part with you, which is why I won't exclude you from this stage in my life.
For now, I'm not changing anything. I will insist on work when I can; the doctors will insist on rest when I must. If you see a little less spring in my step, if your name fails to leap to my lips, you will know why. And if I tell you a funny story for the second time, please laugh anyway.

Isot ma drüe, Isot m'amie
En vus ma mort, en vus ma vie.

Context: I gave you my life, you gave me my life.
Like a gush of wind in my hair.
Why do we forget what's been said
And play the game of life with our hearts?
