My brother is a big think it all, although in a nice way, however he was consistently reading & studying something new. Then once he learns some current facts, he then proceeds to rattle them off to me & our family. He doesn’t only memorize facts though, he will pinpoint a subject of interest & then learn everything he can about it so he gives us it’s an entire history in a documentary-like voice. It can be kind of interesting & fun to learn, however at the same time it can get actually seasoned actually fast, and regardless of whether it nervous us or not, he would continue on. His past subjects of interest were cars, candles, calligraphy, telescopes & metal… Now he seems to have focused his interest on HVAC related stuff. He starts off by telling me small little facts, enjoy what the cooling system filter does, or what the cooling refrigerant is meant for, but I think it won’t take long before he starts diving deep into its history, & then enjoy a parrot, repeating all that he’s l gained. I’m blissful he’s taken an interest in several things, but I have no interest in heating & cooling stuff. As I figured, he doesn’t seem to care that I don’t love his heating & A/C stuff, & he continues to tell me about it anyway, however just sureterday, I saw him with his arms full of HVAC books, all with odd stuff on gas furnaces, air conditioner, cooling system ducts & more. I just silently shook my head, & knew that later I was going to be getting an earful of HVAC knowledge.
