Allergies

Odd way to start off the first lesson wasn't it?

Why were they telling her that they were allergic to things that weren't in the room, as far as she was conserned Proffeser Lafay didn't let in a cat nor was she having a bar of chocolate! Besides she didn't think she was allergic to anything in the room.. Possibly a reaction from dust or flowers, hayfever! But not any praticular ingrediant used for Potions as far as she knew... or thought!
