I wonder that if you really believe in Hallowe’en, and if you happen not to be dead (or undead) yet, then “happy” isn’t really the appropriate adjective for this evening’s unnatural occurrences. More likely “scared witless”. So, if you are planning to celebrate around about now: Happy Hallowe’en, Samuin, Calan Gaeaf, or whatever else you may choose not to believe in at this time of year.

PS I notice frequent comment contributor mpj has been getting into the Hallowe’en spirit, with this cheerful and irony-free sign in front of a graveyard.
