Kid: ARGH! (louder, if possible)
Me: Honey, STOP.
Kid: ARGH!!! (arms flaying, running around blindly)
Me: (grabbing her) I need you to stop freaking out - you're going to hurt someone or yourself. What's going on?
Kid: I HAVE LENT IN MY SIGHT!
Me: You have what in your what?
Kid: LENT in my SIGHT!
Me: What hurts?
Kid: My eyes! My eyes!
Me: Sweetie, what's in your eyes?
Kid: LENT! LENT!
Me: What's LENT!?
Kid: Little dust balls! AGH! AGH!
(after thinking a moment...)
Me: Do you mean you have lint in your eyes?
Kid: THAT'S WHAT I'VE BEEN TELLING YOU!!!
