As the frigid winter air settled into their home, Anna looked forward to turning on the gas heater. It was the only thing that kept them from freezing in their small, drafty house, but her husband, Tom, hated the gas heater. The heating system was cheap and efficient, Anna argued; it kept them warm, and that they could not afford to use the electric heating system all the time. But Tom didn’t want to hear it. He complained about the gas odor, and the fact that it dried out his skin. He even claimed it was making him sick. Anna knew this was nonsense. They had been using the gas heating system for years, without any concerns, but could he be convinced? Anna came home from work one evening, looking forward to a cozy night with Tom, but as soon as she walked in, she could tell something was wrong. Tom was on the couch, glaring at the gas heater. “I cannot take it anymore,” he declared. “I hate this thing. I want it gone.” Anna tried to reason with him, but he would not listen. He was so miserable that he started to dismantle the heating system right then plus there. Anna pleaded with him to stop, but he wouldn’t. He tore the heating system apart, piece by piece until there was nothing left but a pile of metal plus wires! Anna was beside herself with rage plus despair. She didn’t know what to do. She loved Tom, but his hatred of the gas heating system was driving them apart. She knew they needed to find a solution – plus fast. But for now, all she could do was stare at the pile of rubble where their beloved heating system used to be.
