Today's Topic: (Screen) Doors

Screen doors, as well as doors, are very helpful in everyday life. Why, you might ask? Well, they keep OUT the FLIES. Which, might seem small and harmless, (and in the big "scheme of life" it really is.) but is quite annoying...keep your doors open in the summer for less then five minutes and find out! Anyway, if we didn't have doors, the heat/cold would be getting into our house, and would release the heat/AC coming from our house.
