OK, so WW overheard a call with my mother, but only the last part where I said, she's not going to be here, but the doors going to be open so let yourself in.
WW asked who, I said no-one. She leaves in skirt and boots and sneaks back in ten mins later, as I put our S to sleep. Then my mother comes around with cake and my Ww pops out of the second room in pyjamas. I'm like. DAMN.
Just cos things are going right, doesn't mean that they were always wrong.
