Why is it that I will sigh with exasperation at Christmas adverts starting on TV at the beginning of November but bite my lip in anticipation when I see the lights going up in Covent Garden?
Why is it that Christmas windows in shops in October give me a heavy heart but seeing the Christmas magazines on shelves this week made me eager to hand over vast sums to the newsagent?
Why is it that I felt an excited flutter when I realised that Sunday's Observer Food Monthly would be the Christmas special?
Why is it that I realised that I could finally pull out the Christmas books again (Nigella, Delia, Sarah - sigh) and, most worrying of all, why is it that I found myself humming a Christmas song today?
I blame the smell of mulled wine in the evenings.
I blame the lights which have been up in Stoke Newington for a little while now.
But really, I'm a sucker for Christmas, I can only blame myself.
