McGonagall: Albus, I think we need to make some alternations to the Hogwarts letters.

Dumbledore: Oh?

McGonagall: I think we should tell Muggle-borns how to get onto Platform 9 3/4.

McGonagall: You know, just in case flat out sprinting towards a soild brick wall isn't their first thought.

Dumbledore: I'm not going to do that, Minerva.

Dumbledore: once a year I like to watch panic-stricken Muggle-borns running all over Kings Cross  station while I'm invisible. Is that so wrong?

Dumbledore: It's the little things, Minerva.

McGonagall: Albus.

Dumbledore: Why are you trying to take that away from me?
