Oh, oh, oh, no. We don’t know where to begin. This person didn’t just let an awkward moment pass; she actually actively decided to make it even more awkward for anyone within a five-mile radius of this exchange. Why, oh why would you do that to yourself?
Basically, the BF’s mom joked about the OP and her BF making babies, to which the OP responded that they’re enjoying practicing the baby-making process. This, however, wasn’t a total let-down for the mom. The OP and her husband are now engaged. Mazel tov, we guess, but try not to do anything that’ll make your future MIL cringe herself to oblivion.
