So, my MIL called the other night while my husband and I were... busy in another room. We let the answering machine get it. A little later, my husband listened to the message and called her back.
"Hey, Mama! Sorry, we missed your call. No, we were intimate."
. "DH! Did you just tell her that???"
A few minutes later, he was off the phone. No, apparently he *hadn't* said that. She'd asked if we had been out, and he'd said, "No, we were in tonight." I don't think I've ever been as glad to find out that I'd misheard somebody in my life.
