Who are the
pencil hearts in
your spiral notebook for?
Do you even know? (No.)
Do you want to know?
(I think so.)
I want to find out,
but I'm so confused.
These drawn-on hearts
hold secrets,
I just can't pick one.
(Can't choose.)
None of this seems fair.
He holds my heart
in the palm of his hand;
to toy with,
'till he gets bored
and then forget.
Forgotten until the next time
he needs a playmate.
(Emphasis on mate.)
Is this love or hate?
I'd rather not choose now,
but there's no more time to waste.
