Her (imperiously while lying on the bed): Mummy, MUMMY, MUMMY!
Me (toiling up the stairs, muttering mutinously): This had better be a real emergency.
Her: Utterly trivial request.
Me: Moan, upstairs, groan, three children in this family, grizzle, world does not revolve around you etc. etc.
Her: Reiterates utterly trivial request.
Me: Do you understand? I do not want you to just lie there shouting Mummy, Mummy at the top of your voice when you want something.
Her (seriously): Would you prefer me to ring a bell?
