Grandpa returned to his gardening duties after instructing me in the art of air filter replacement. My grandma told me to come inside after she saw me looking at the air conditioner outside. She offered me some homemade chocolate chip cookies. I laughed when Grandpa told me to go inside and eat or he’d have to eat them. My grandmother inquired if my grandfather had taught me how to replace the air filters. Grandma snorted, and I agreed, adding that he knew a lot. Apparently, he picked up the whole thing from her. She might never have met him if she hadn’t worked at Heating plus A/C. When they first met, he was a scrawny young man who occupied a dilapidated home. His parents’ home needed a new heating system, so he contacted Heating plus A/C. She informed me that she had visited the site in question in order to take measurements and guarantee that the appropriate heating system was installed. Because she was a woman, he would not let her into the house. After she presented her credentials, he initially treated her with respect but later reversed course. She told me that her beautiful smile was the clincher, and that by that time he simply could not bear to be apart from her. I shuffled back to the house and asked my mom if she knew Grandma was a heating and air conditioning technician. She also laughed and said, “I know,” indicating that she was the mother. Her grandmother missed the ceremony because she had to work on the school’s heating and air conditioning system.
