Seneca, I know ToT derives from guising, and that's fine. Customs change over time, we don't stick decapitated heads on spikes round the village any more (the origin of lanterns, whether neep or pumpkin, apparently) and that's fine too.
For some reason, guising didn't spread beyond the Celtic fringes in the UK. It went to the US with emigrants, and changed a bit, and now we all watch American telly the changed version has "come home", and spread to the rest of the UK.
Now some in rUK complain it's American (as if that's some terrible sin) without ever even knowing about the origins. It's that ignorance that irks, that some of us have been celebrating Hallowe'en for generations and we're the next door neighbours, how come it wasn't noticed before?
And to see our thousand-year old traditions "taken over" by ToT in our own homeland (rUK can do what it wants) makes me sad, and thrawn about insisting on the word "guising", and dookin for apples, and sticky scones dangling from above, and all sorts of other superstitious bollox, if that makes any sense?
