1. The almost fanatical need to be outside for every minute the sun is in the sky
Although I come from the sunniest part of Britain, the very British habit of dropping everything to be out in the sun for the fleeting moments it deigns to shine was very much part of my life before coming to Madrid.
The idea that I would be inside writing this with the blinds down on a beautifully sunny day at four in the afternoon without having ventured out of the house all day would appall the me that used to rush outside to have breakfast, read a book or head to the park at the merest glimmer of sunshine!
