Most of the time it's right in front of me, but my brain is just shortcutting over it.
It's become a running gag in my house that my wife will set something down on the floor so that I can't possibly miss it, like a laundry basket that needs to go downstairs, and I step over it without thinking.
One time, late at night, I went to my son's bedroom to make sure he was asleep. His bed was empty. As I was leaving, I saw him asleep on the floor in the middle of the hall, which means I'd stepped over him.
Sometimes I just don't see things.





When I learned about germs, how they're everywhere and too small to see, I thought I must be squishing them every time I touch anything. So I went around the entire house touching every surface, especially the windows, because nobody ever touched those.
