In our kitchen is a garbage chute. Above the chute is an illustrated diagram of all the items one cannot throw down the chute. Among them is listed recyclables, cardboard, plastics, bricks and fire. Bricks and FIRE. It is forbidden to throw out FIRE. And BRICKS. Thankfully, all of the bricks I had brought from Canada I threw out in the airport washroom (along with my chewing gum).
