Spare

I’m not sure why
a four wheel drive
missing its spare tire
made me think of you.
But I have left the sun,
brilliantly yellow, behind me
at least half an hour ago (maybe longer)
and now the moon
(surrounded in a purple dusk)
is within my grasp
and I feel I know
the tire is not missing,
but being used.
You always seemed
the kind that would
need their spare.
Maybe you’ll need mine too.
I can’t see myself
using it.
