So I’ve upset my elderly mother because when she reminded me not to mention a family pregnancy to someone because it is a secret, I laughed and said it couldn’t really be a secret if they told her (to be clear, I’m not telling anyone). I meant this in fun, but it is true that she just can’t keep certain secrets- case in point, I know about this family pregnancy from her.
She is upset that I think of her like this, but I don’t really know how to row back as it is blatantly true (this is a regular thing). AIBU?
