I would not say you were new
when I first laid eyes on you
deflated beneath children's junk
I picked and placed you in my trunk
that was summer, now its winter
your cracks converged into splinters
having stretched around your globe
from heat to toe, lobe to lobe
receiving you from children who had
more than I and weren't a bit sad
their paths would no longer cross
and could have easily been tossed
away for they since had another
a non-leather-like brother
and long ago lost your grip
and slip away through finger tips
so I got out my bike pump
squeezing until you were plump
