When I first read those words in my list of instructions after my tooth was removed, I thought—weird—well, I won’t have a problem with that don’t do.
Later, as I was brushing my teeth, I automatically spit into the sink. Oops…I wasn’t supposed to do that.
Then, as I whished my mouthwash around to cleanse my palate, I spit again. Oops…I wasn’t supposed to do that either. Maybe this rule will be a problem after all!
