In my next door neighbour's house the recognised fact is that a group of children only enjoy themselves by shouting randomly and persistently at the top of their voices. They seem not to receive any reminders about calming down or modifying their hollering. They can keep it up for hours. Fortunately, only one of the children is hers, and this only happens when her friends bring their kids round to make up a sort of little shouty gang. For some strange reason, they have now deemed the volume to be not high enough with unamplified voices and for Christmas, she introduced some sort of machine that lets you shout along with the stars, karaoke-stylee. Who on earth invented such an abomination? Surely the work of the d***l?
