Ok.
We can do that.
Take some chlorine from your paddling pool, throw it about the bedroom a bit. Leave very wet odd socks on the floor, and a few tissues.
You and ds3 take a shower in your swim suits.
Get ds3 to scream and refuse to sit still while you put his socks on.
Speak in Brummy accents (perhaps you already do.)
Stuff a pillow up your shirt.
Then lights, camera, action ROLE PLAY.
Will come back to you. Will be like muscle memory.
