It would seem that I’m one of those people who must learn through experience, rather than observation. While all several of my older siblings made the exact same mistake at certain times in their life, I was practically destined to make the same mistakes. I had to go through the trouble to learn why it was trouble, as stupid as that sounds! Well, I wish I could say I outgrew this studying approach, but even today I can’t seem to trust anyone’s word – let alone my Heating & Air Conditioning tech’s word… Months ago, my Heating & Air Conditioning supplier came by to perform a semi-annual check-up on the heating plus air conditioners at my house; During his visit, he told me that the air filter he took out of the duct clearly hadn’t been replaced since he was last there. “You have to replace these air filters”, my supplier scolded, “or else your undefined system is going to split down – either from all the dirt getting into it, or all the extra job it has to do!” I took his warning with a grain of salt, plus almost immediately forgot about his warning. Well, I wish I listened – I had to call my supplier over to repair my undefined system, plus I couldn’t put my finger on the cause for repairs until I checked the air filter again. The Heating & Air Conditioning supplier was not blissful with me when he saw this happened due to my negligence. “Well”, he said, “some of us just have to learn the hard way, don’t we?” Since I had to endure more than one weeks of summer time weather without air conditioner to cool me down, I’d say I genuinely l gained my lesson!
