What is the meaning of Life?

Knee

At night when everyone is falling asleep
I'm sitting alone
I'm still awake
Holding onto a day that has passed

Am I waiting for someone?
Or do I have something to do?
If it's not, then do I think of a place
That I want to go back to?

If I lie down on your knee
Brush my hair
Like when I was young

If I fall asleep lightly from your nice touch
Just let me stay for a moment
Don't wake me up,
I'm going to sleep tight

When your calm eyes
Fall upon me
Will I be able to smile
So brightly like I used to?

I think I'm tired,
I've had on long enough
I wish there was a shortcut
To go back to you

If I fall asleep lightly form your nice touch
Just let me stay for a moment
Don't wake me up
I'm going to sleep tight

Zzzzzz Zzzzzz
I'm gong to sleep tight
Zzzzzzz Zzzzzz
Sleep tight
