I am a happy man. But I own't be happy if my irritating relatives come for Xmas. They have already told me they intend to, and I have told them I would rather swim in sewage. They don't believe me. They are intolerable. My aunt stinks of stale butter and my uncle harps on about gardening and hats. My mother eats in a strange way and my nephew is some sort of goth.
How can I tell them not to come and bother me, in a way that will still get me presents?
