Basically, point being, we sometimes do what our mothers did for absolutely no other reason than that's the way our mothers did them.
I realized tonight that I have one such a story.
I was vacuuming this evening and realized that somehow my vacuum height had changed from "lo" to "medium." I pushed it a few times to make sure it got back to low immediately. Why? Because that's what my mom always did. I truly have no clue what setting -- extra lo, lo, medium, high -- is best for my carpet. No clue at all. I'm not even sure the pros and cons of each of those settings. What are they even for? But what I do know is my mom always made us vacuum on low.
It's set on lo!!! Neurotic's honor.
