Me: Ok, what's that?
Mother: Well, I can't remember exactly what happens when you've got it, but it's bad and rare.
Me: What's it called?
Mother: Paget's something or other
Mother: That chap from the Paget invented it.
Me: You mean 'James Paget'?
Mother: That's him. He invented it.
Me: He didn't 'invent' it.
Me: He 'discovered' it.
Mother: Well that's the same thing.
