the future is a prospect yours not mine

I.
the future is a prospect yours not mine
whatever slope you'll clamber and not regard who's left
I'll watch you recede, and wonder at the day
you rose so quickly and without my fear
that the future was a prospect yours not mine

II.
A day with you as any other day
but you are not the you you were
Traces linger (Sprite with your dal) but
now you are past my shoulder
The future is a prospect yours not mine

III.
white mountains
each day for me and I think so few days
each day for you to clamber and recede
sometimes I think I'll lose you at the verge
you'll topple and I'll be here and I'll be here and
the future is a prospect yours not mine
