I'm usually pretty observant about things around me, but especially regarding things about me or on me. I rarely put on two different socks or accidentally put on a shirt inside out. If I do, I notice immediately and fix it.
When getting ready for bed I noticed that one of my socks was inside out. Not that big a deal. But it was that way all day. It's not like I went anywhere and I was embarrassed by an inside out sock that no one could see. But I never noticed it.
There's a lot going on right now. I can't say that I'm surprised.
