There are so many great rectangles -- remember, squares are also rectangles -- that it is hard to choose a favorite.
Football fields, soccer pitches and basketball courts are terrific rectangles that contain even more useful rectangles! A hockey rink is not a true rectangle, but its unique penalty boxes are. Photographs are reminiscing rectangles. Televisions are entertaining rectangles. Computers are idea rectangles. Business cards are networking rectangles. GED certificates are low-achievement rectangles. Counties in Texas are xenophobic rectangles. Political bumper stickers are douche bag alert rectangles.
My bedroom is a rectangle with two rectangle closets and a rectangle bed. My bed is my favorite rectangle.
What is your favorite rectangle?
