God bless my MIL but she's been sat in the room adjacent to the one I'm in for the past hour and a half, yawning constantly...it's nighttime here...and she needs to go to bloody bed!
She always does it and it drives me mad! I'm thinking JUST GO TO BED!!
The yawns are litereally every few seconds....and she voices them....so it's not just a silent yawn but it's got an "Oh" in it iyswim.
