I got a new air conditioner for my bedroom this summer, and my brother took it to my apartment set it up even though he kept going on and on that I was going to freeze with it on. He seems to think my bedroom will turn into a walk-in freezer and I will end up frozen in a block of ice and die of hypothermia just from having the AC on, even though it gets very hot in my bedroom during the summer, having just a fan on or opening windows doesn't really work, and the coolness of the AC is adjustable. Or maybe he believes in "AC Death Syndrome", like how people in Korea believe in Fan Death Syndrome. Whatever the reason he nearly drove me bonkers. But I did appreciate him setting it up for me.
My mother admitted to me he had been driving her crazy during his visit at her house as well. When we were head over after shopping she called and told him to put the lasagna she had made for us in the oven. The lasagna was all ready to be baked, he just had to put it in the oven. But he acted like this was a very complex and confusing thing to do. Of course when I mentioned what mom had said about him later he acted all innocent. What a character he is.
