I remember once when I was young, looking out into the sunset
and thru the sky a long stretched line was spread, the tail of a jet.
Beautiful.  Purple.  Orange.  Red.
I remember staring off, trying to imagine myself standing on the horizon's edge.
I thought, what magical wonderful things could there be beyond the end?
Is there anything beyond the horizon?

Now I'm older, as I see that line's been like a rainbow to me.
It still reminds me it's here.
Fades away when I get near.
It's not as beautiful, regrettably so.
Guess there's something sublime about things we don't know.
Perhaps life is that way, when the horizon is gone.
We just can't see, but it also goes on.
