In all these years hanging around blip I have only asked strangers twice if I can take a photo of them. I think I do it so fast that they don't really hear the explanation and do it to get rid of me

Anyway these two were next to me and Liz at lunch and eventually had to ask why the jumpers? Apparently everyone knows about Xmas jumper day apart from me. But maybe that comes of avoiding shops at this time of year and having no office full of jumper-wearing pals.
