At this point, being a mother-in-law who respects a couple's boundaries must feel like being a patient and understanding woman who happens to be named Karen.
But while I believe either one when they say in frustration, "I swear we're not all like this," it's still easy to understand why the stories of other people's worst behavior tend to get the most traction.
After all, not only is it is obviously abhorrent to most people when a mother-in-law wears her wedding dress to a bride-to-be's wedding or secretly changes her grandchild's name to something she prefers, but it's also behavior that many of us wouldn't have imagined until we heard about it.
However, other cases of a mother-in-law overstepping boundaries tend to be a lot more common, which is likely why one story of subterfuge resonated with so many people.
