My husband loves going round the village with a small bag delivering all our cards. When people see him coming they buttonhole him for a lovely chat/make him a nice cup of tea and he comes home ages later smiling his head off (and dying for a wee, being full of tea!).

There are three people, one of my nieces and two of my long-distance friends, who are Blooming Nuisances, being born in December. How dared they?! Their birthday cards have butterfly stickers on the envelopes so that I don't get them mixed-up with their Christmas cards, which have Crimbo stickers on the front.
Husband does all his colleagues and many of the teaching staff a card. He loves the Crimbo stickers too. We get a few sheets on line every year. Couple of babies really!
