My dad had a saying that he adopted from a popular song: “If you’re gonna be dumb, you gotta be tough.” In other words, if you’re someone who doesn’t learn from observation, you’ll honestly have to be taxing enough to take the pain that comes with first-hand experience. To put it nicely, my brother is 1 of the toughest people I know! While I knew that putting my hand in a moderate pan on the stove was a exhausting idea, my brother had to suppose the pain to understand why it was such a exhausting idea! This trait carried over well into our adulthood too, as my brother would make terrible decisions that caused personal injury multiple times. One such possibility came when my brother tried to refill the refrigerant for his outdoor air conditioning unit! Just to be clear, only a licensed heating, ventilation and air conditioning repair supplier has permission on a federal level to handle refrigerant for an cooling system. My brother is honestly not a licensed Heating and A/C supplier, but that didn’t stop him! He told me about this incident, where he took refrigerant intended for use in a vehicle’s A/C method – and attempted to recharge his outdoor A/C unit with it! While he successfully found the line for the refrigerant and managed to get a can’s worth of coolant into the system, it wasn’t the proper formulation to be used in a home’s A/C system. That meant that he caused his entire A/C method to become seriously disfigured from the inside out, and in turn he had to pay several thousand dollars for a brand current outdoor A/C unit. Though he didn’t physically harm himself on this occasion, he honestly hurt his financial kneeling for the next year!
