I also better be sure to set an alert on my phone, and wake him if he is asleep!
I've made the mistake before of doing some positional thing he didn't really want, then to have him go into a very sound sleep ...
Then wake, of course when I am out of ear shot, and I come in to a distressed, angry man who seems to think I left him there too long on purpose!
The other day this happened, I kept checking on him every 15 mins or so, and gardening, he didn't wake to me speaking to him, and sheesh don't you let sleeping dogs lie?
Well the pharmacy kindly were delivering some stuff to me, and I realise I can hear this voice, and come around the front to find this lady standing at the door to the lounge room (my PALS room) and calling out 'hellllloooooooo' for all she is worth. I explain my husband was asleep and thank her prolifically when I realise who she is and off she goes abashed. I come in that door, letting it just bang, certain he is awake, and no he is still sound asleep.
Man, 10 minutes later when he woke though .... uh oh, I had left him in that position too long and I had hell to pay!
Rock and hard place!
So yeah, I will just wake that sleeping dog next time
