She’s always saying bad things happening, like lost keys or a chipped tooth, can turn out to be mixed blessings, but when you encounter the good and the bad so clearly, I don’t think the blessings have been mixed thoroughly.
She’s also bad with mixing oatmeal, and I hit dry patches of unmixed oats among the lumpy mush in my bowl.
If you chip a tooth on oatmeal and you’re told “Well, don’t think of it as a trip to the dentist, but think of it as a day off of work” that’s not a mixed blessing. That’s badly-mixed oatmeal.
