The drone of fans filled the tenement building, dozens of plastic and aluminum blades filling the silence and stirring the humid air. Unfortunately the air in a tenement building is not longed-for fresh air. Any open windows bring in car fumes, garbage scented dumpsters, and animal deposits, especially in summer heat. If you are on the inside of the building without windows, you are subject to Grandma Willy’s home cooking which is a delight or a curse depending on what is on her menu. If you are lucky enough to live in a corner of the building you may get a cross breeze placing a fan in one window and pulling the air through another window instead of blowing around inside stale air. Air movement of any kind can be a blessing sometimes.
