the twitch

your eyebrow twitches
when you think of her,
when you hear her voice,
or see her name
on your phone.
it's a small tremor
along a strangled thin
nerve, a nerve she found
in you. when the phone
rings and it's her,
the eyebrow bristles
and jumps like a caterpillar
trying to become
a butterfly. she's found
a way to get under
your skin and stay there.
