A Heidi
A Heidi is the girl who'll love you to death, but don't mess with her or she'll make you wish you were dead.
Heidi said I was 'the most annoying person in the world' when I stole her fries.
Heidi threatened to cut my hair if I didn't stop talking during her math test.
Heidi said she'd 'bite my face off' if I didn't stop teasing her brother.
