Objections to Halloween can take many forms; the fact that it's a celebration of Satanism or that it's an essentially American tradition that we've imported in all its gaudy, tacky glory or that it legitimises scallies knocking on your door all night and doing what is essentially begging - and in doing so clogging the path for Spanish art students who have a giant portfolio of watercolours to show you.

Still all those objections melt in the irrestible picture of Olivia in her witches outfit. As can perhaps be seen in some of the scowls that Olivia is flexing for the camera in recent photos, the days of her firing off a beaming grin at the merest glimpse of a camera, are now long behind us, and it takes a great deal of cajoling - as well as an off camera sky remote - to coax anything resembling a smile from her.
