Once a baby
and then old
huff and puff,
the mid ones knit brows
troubled thoughts.

Lack of energy
limited spirit
hold oldies back
while babies haven't got it yet.

Middle wonder, this energy:
baby: it should grow faster
the old: should decrease slower.

Neither baby, nor the old
could really explain
a paradox really
true confusion.

The shoe pinches
for the wearer.
