I dressed up as Severus Snape (rather convincingly I thought, I'm good at scowling and my hair looks greasy even when I've washed it,) then went trick or treating with my niece who was a pretty little witch. Who then had a strop because she had to brush her teeth and go to bed, you'd think she was being murdered. 
Earlier in the day I'd turned up in Oxford in a rather more circumspect get-up (I looked a bit like Bellatrix Lestrange,) went to a lecture at the Ashmolean Museum titled 'The Fear and Loathing of Witches' which was rather interesting, met my mum and then we went round the Spellbound exhibition which is also about witches. (Notice a theme?}
The horror bit was spending nearly four hours travelling in order to get to Oxford, and the realisation today, amongst all the Christmas crap everywhere, that for most people Halloween is over. It's not! it doesn't finish till tomorrow night, at least not for me. Halloween is my favourite time of the year, because of a strange mixture of Paganism and Christianity that I hold dear to my heart, and it's the only time I can feel 'normal'. It's probably a Goth stereotype to love Halloween, but oh well.
And another thing, my great-grandmother died on Halloween night 22 years ago, my mum has only recently got her ashes back. My nan also died a few years ago. Yesterday my mum gave me a pendant that has a little of both of their ashes in. Made me a bit teary.
