Overprotective Mother
Some parents can be too overprotective for their own good. The second this mother came home, she’d immediately check up on the baby like nothing else mattered. The OP knew how important the daughter was to the mom and asked a super-personal question that they probably shouldn’t have asked.
“Have you ever thought about having another?” As soon as the words escaped the OP’s mouth, the mom broke down and started crying. Apparently, she and her husband had tried multiple times to give their daughter a sibling, but every pregnancy ended in total devastation. Should’ve learned to mind your own business, OP. Now, even we feel terrible about the poor mother’s situation.
