Poison berries

Red berries are poison berries,
that is what her mother taught her.

Men who grab you,
and don't let go,
even when you say no,
are just like those berries,
that's what her mother taught her.

"Why?" the girl asked.

"Why?" her mother said,
"They will kill you fast or kill you slowly, 
they will hurt your heart and leave it black and blue."

Her mother took her hands,
locking their gazes and said,
"So fight, my daughter, 
watch, my daughter."
