I think it’s because of the steps removed you are from becoming non-naked. With no shoes, you’re simply an underwear away from being non-naked. But with shoes on, you must bend over, remove your shoes, remove your socks, and only then are you free to install underwear on your naked dingaling. Now imagine if your landlord unexpectedly knocks at the door, and you were naked with no shoes versus with shoes. In the first case, you’d be non-naked in a matter of seconds. Whereas, in the second case, you’d be non-naked in about 15 seconds. Not to mention, you’d be in a very compromising position during those 15 seconds, as you’d be bent over in a strange position fiddling with your shoes over your own naked body. Never discount your brain’s ability to plan ahead. And don’t think this all isn’t taken into account when considering how naked you feel with or without shoes. This, I believe, is one of the primary reasons. Okay, thank you for coming to my TED talk, have a blessed day, and fare thee well!
