My mum's definition of "summer" is as simple as it is true: It's the time when all activities normally performed indoors is moved to the outdoors.
I don't want to sleep at night because it's so light and warm. And I don't want to stay in bed in the morning because it's so light and warm. I want to do all my eating, working, reading, partying, playing, writing, knitting outside. And I do!
We are having the best summer in Sweden this year, better than in a long time :)
