A Desperate Riddle



I fall to you forever,
But you are not reached.

I give you light,
But I do not shine.

You give me one moment,
Ignoring me in all others.

When I'm not in front of you,
I'm behind you.

When your shadow covers me,
I am invisible to you.

You fall forever toward another,
I fall to you forever.

You are fertile,
I am barren.

You hold to your belongings,
Mine are often lost.

Your life-giving water is free to all,
I keep mine frozen, below.

Who are you and who am I?
Who am I and who are you?
