Don't feel crappy by her

If your cheery and happy
Then don't call her crappy,
Cause she never laughs
and stares at all staffs,
She's probably a goth,
And compared to a moth,
she wears dark clothing,
and always starts loathing,
but if you went to her with a feather...
she'll squirm and she'll say,"Stop trying, Heather."
