Read the extended metaphor poem below.

Bat

My son is a bat.
His eyes blink when darkness comes.
His body stirs with life.
His limbs gorge with blood
as he sets out through the cave of night
his roof the stars
the moon a big white eye watching.
Attracted by the false lights
he mingles with his batty friends
weaving in and out of nightclubs
endless parties
each other’s places
till sensing the sudden ebb
of darkness
he flutters home
a cloaked Dracula
to the hollow of his room
where he will sleep all day
