Hey you. You like to include everybody, right?
Did you know that 10% of the world lives in the southern hemisphere, where it isn't summer?
40% of the world lives in the tropics, where they don't even really have summer – they have wet and dry seasons.
Please stop naming things after the seasons.
(Don't apologise, to me anyway. I find this more amusing than annoying. And I enjoy reminding people that the rest of the world exists.)
