I've recently come to the realization that playing well in doubles includes getting/helping your partner play well.
So I have been working a lot on what I can do to make my partner play better. Either shoring them up when they start to wobble, or snapping them out of it when they go into a slide.
Saying "I would've held serve if my partner didn't miss those two overheads." somehow isn't very reassuring to me.
We stopped checking for monsters under our beds when we realized they were inside us.
