My sibling is not really an HVAC expert

My sibling is what you might refer to as a serious know it all! He is so irritating, and to me, he always has been.

He truly thinks that he’s an expert when it comes to everything.

This past year, over the holidays, I was actually prepared to smack him because he would never stop talking about Heating & A/C appliances and all of the things that he knows about that. The thing is, he doesn’t really know anything about gas furnaces or air conditioner appliances! I’m actually the one who is a certified Heating & A/C specialist, however my sibling wants everyone in our family to actually believe that he knows what he’s talking about. I’m sure you’ve met someone similar to this before, or you might even have a single one of them in your actual family. They are seriously annoying. I actually know for a fact that the only thing my sibling knows about heating and cooling appliances is how to adjust the temperature control unit in his own dwelling. He actually acts as if he knows it all literally all the time. I personally think that this is the very reason that he can’t get a bestie to stay with him for more than a week or two at a time. He’s just irritating to be honest. This whole thing with him acting as if he knows everything about Heating & A/C appliances is sincerely the worst. I think it’s honestly just because I really do know truly everything about heating, air conditioner, and ventilation. I mean, of course, I can always learn more if I am being honest! But when it comes right down to it, I’m sincerely the one that is a professional, not him. When he acts as if he knows what he’s talking about and it’s so clear to me that he doesn’t, it makes me feel that I can’t even be around him.
