A square at a time

There is a boy at school,
with a small chocolate bar,
who sucks and nibbles a square at a time,
slowly.
My bar I push in whole
to a mouth impatient,
chocolate melts into every crevice
jaw immobile, crammed full, demanding
for a moment;
that falls away and leaves
guilt and desire free
to resume their endless war.
Rare stillness,
I sit remembering
the boy with the chocolate bar
who eats a square at a time,
carelessly
