Spider eyes

Did you know spiders have eight eyes?
he said,
his eyes bulging.
Really? I said
(thinking he might
have mixed up
eyes and legs–
he was only four).
But a few months later
he said it again
and then again
(even after he turned five).
So I looked it up
and, you know,
spiders really do
have eight eyes,
usually,
sometimes six
rarely two
and Did you know,
I’ll tell my young friend,
some of their eyes
GLOW in the dark?
