Elves, Dwarfs, and Me

So Ethan came up to me today and asked if Elves were real… I told him no, and he said" but Dwarfs are right?"  I told him that Dwarfs are not a race, but a condition that some people have which causes them to not to grow as tall as normal people would…. He looked at me and totally serious said “So, you’re a Dwarf then?”
