Kat, in defense of my ex, I'm pretty sure that she never actually woke up before she whacked me upside the head. And while I like the idea of a back rub, I only snore when I'm on my back — if I sleep on my side (as I've trained myself since I started sharing a bed with my current wife over 25 years ago) I don't snore.
OTOH, while my wife snores, she's quiet enough she has to be sleeping on my shoulder for me to notice. Hmmm... y'know, I could rub her back with very little effort in that position. I think I'll start doing that. Thanks, Kat! 😊
