I managed to change my name for the very first time for Hallowe'en. GhoulsGhouls, since you ask. I'm thinking maybe YulesYules for Xmas, or possibly a Scandi flavoured JulJul.
But not before 1st Dec, obvs.
And I don't do my tree until 18th December, no matter how much the dds sob and beg and say "Everyone else at school... " I'm tough, me.
