Audrey comes back from the toilet. Kelvin, Joshua and Hannah were talking about driving.

Audrey: Oh! I have no more P! Yay!
Kelvin: *looks at Audrey funny*
Audrey: I have no more P.
Kelvin: *still looks at Audrey funny*
Audrey: I have no more P! As in I have no more P!
Kelvin: *STILL looks at Audrey funny*
Audrey: What? Oh! I dont mean I have no more PEE.. but yeah, it's true I have no more pee. But I meant I dont have P anymore as in my DRIVING LICENCE is no longer a P licence!
