I have suggested here before that knowing and doing are two different things.
Here's another lesson I'm re-learning. You know when you're vacuuming something above your head? Like in a tiny space, like an attic? And it's just so disgusting, like buggy and spidery and cobwebby and you pretend those can't be rodent nests because if they were you would scream like the cowering 10-year-old you are inside and be SO outta there?
That's when you should keep your mouth shut. Yes.
When vacuuming a surface over your head, close mouth.
Of course, "close mouth" is not bad advice for me in general.
