When he was little, my child Albert used to pretend to maintenance the heating system with his little pretend tool set. It was typically super cute and my wife and I enjoyed when he did that. Hhe had a little tool belt with little plastic tools on it and he would go around the house hammering on things and pretending to maintenance them. One day, we had to have our electric boiler inspected and when the heating and air conditioning tech came to the house, Albert thought that he was the coolest thing ever. Hhe watched him like a hawk the whole time that he was there working on the heater. He asked the heating and air conditioning tech if he could watch him work on the boiler and he told Albert that he could. However, Albert lost no time at all grabbing his tool belt and heading down to the basement so that he could help the heating and air conditioning techncian. I was happy that he was going to get to watch the professional working on the boiler because it was his number one thing to do. I never knew a little boy would be so happy to work on cars, heating and air conditioning systems, appliances, and mechanical things. The heating and air conditioning tech was a truly wonderful sport and he taught Albert how to change the air filter in the heater. I was legitimately impressed with how kind and patient he was with Albert. Albert ended up having the best time! He talked about it for weeks after it happened and now that he’s an adult, he’s a heating and air conditioning tech himself.
