first cousins

Sinatra is singing
fly me to the moon, while we slow
dance
across the floor,
me and my cousin Marie.
we've both had a few cocktails,
and almost kiss,
our lips dangerously come close
to one another.
which would be scandalous,
seeing that she is
my mother's brother's
daughter,
first cousins.
but we get along so well.
we dance together
and laugh, and think the same
way.
we both like jello.
what is it with these archaic
laws.
why don't we live in England?
