Time above the earth

I've spend so much time above the earth
Thinking about life and each man's worth
How can one person be worth more
Than a thousand people knocking on his door?

Still, the motion of your hair
Well, that could take me anywhere
Guess you're happier than I
Please, don't say goodbye

Then I get off the plane
A thousand thoughts reaching through my brain
Like, am I really here, at all?
Will I see her again?
If I do, it'll be the same?
And am I really here, at all?
