Mama's role

Here's the scene...Cora is playing Little Mermaid

cora: mama, i need you to play little mermaid with me.
who do you want to be?

mama: i'll be prince eric

cora: you can't be prince eric because he's a boy and you have to be a girl. Because see your hair, you're a girl. you have to be ursula (the mean sea witch), she's a girl

mama: but ursula is mean. i don't want to be someone mean. (i know, i was asking for it!)

cora : (very nonchalantly as she shrugs her shoulders as to say, tough luck!)
well, sometimes you don't let me eat when I want to (steroid week) and I have to beg and beg and beg and so....you have to be ursula

I'm no moron, if i read between the lines I can get exactly what she was trying to tell me!
