Re: She took over your bed
I’d 1st politely whisper in her ears. “You’re sleeping wrong, which will just get you a neck twitch in the morning, hurry up and flip back”
If she doesn’t and instead decides to smile carelessly while I’m losing sleep then I’d move on to pinching her harmlessly till she flips back to her own predefined space (I’ll make my wife measure the amount of space she needs the 1st night she decides to take over MY bed) of course I’d try hard not to let her catch me red handed. But yes, I’ll get the job done in my own sneaky little ways and without worrying about my scrumptious little serving in the morning.
