Our house in England did not have window screens. The only screen door I saw my entire childhood was when I would visit my grandparents in Wisconsin in the summer. I thought it was so weird that they couldn't just open their windows; they had screens on the inside, and a crank to open the window. And then when we moved to Houston, the screens were on the outside, but I missed being able to put my head out the window. We didn't really have mosquitos, though, it's a bit cold. And everyone just dealt with the flies and yellow jackets.
