When I lived in Brazil, we had window screens, but it was on an affluent area in the coast of Rio. I&#x27;m not sure it made things that much better though. You need a lot of discipline to keep those screens shut all the time when you live in a tropical country and go outside all the time.<p>We just learned that during the summer, around 7pm, it was time to close doors and windows and turn the A&#x2F;C on.
