What Did You Say?

me: Ah my back hurts so much.

my sister: Carmen! Grow up.

me: What the hell are you talking about? I'm lying down and I said that my back hurts.

my sister: GET up.

me: Oh, is that what you said? Sorry, I totally thought you said "grow" up.

my sister: Well actually, I said "grr" up but I was hoping you wouldn't notice.

me: You're an idiot.
