Prongs down so I don't touch the eating end when putting them away.
People with heightened sagacity share in this philosophy. This is the only way to properly load the dishwasher.
ALSO @Sly- Why pick a fight over someones preference? Even if YOU feel the logic behind it is flawed, it's not for you to decide. To he and others (myself included), it makes perfect sense. My father in law lives with us. He has OCD so bad he would make "Monk" crazy. He washes his hands (among many manifestations) ALLLLL day long. He generally has washed his hands into a perpetual state of being raw. I refuse to allow him to touch a plate, cup, or untensil that I or others may eat off of at any time. I don't want his raw skin touching something I'm going to stick in my mouth. Not because I'm paranoid, but because the thought of it happening disgusts me.
As for the fist bump you described. I don't shake hands with large groups of people anymore either. I used to on book tours. Repeated colds, bouts of flu and strep throat made me stop doing it. Now I either give a small wave, a slight bow, or a fist bump.I don't get sick as nearly often as I used too. Occassionally someone will stick their hand in my face, and I'll tell them it wouldn't be a good idea to shake my hand right now. It implies "I'm" sick, and although it may be dishonest, it's better than me trying to explain myself and coming across as some uptight paranoid prick. Even still, sometimes I will shake someones hand, but I generally have to wash my hands pretty soon thereafter. I am a bit of a germ-a-phobe. But more than that, I don't know what someone has been touching that they feel it's okay to share with me.
