I used to go barefoot

I used to go barefoot. I'ld take my shoes off at
the drop of a hat. In the spiky grass, over
the horny barnacles, climbing the smooth lips
of a reclining giant, the large hunk of rock
turned on its side that's Griffith Head, I walked
barefoot. Uncooped feet felt pain not pleasure,
then pain and pleasure, then mostly pleasure,
unless I stubbed my toes or raked them across
the barnacles or a lip of rock not yet smoothed
by the passage of time. Must have been the
passage of time which put my shoes back on -
old age and the fear of getting injured or
the need to spend more time in the "office".
