Reading about pets reminded me I DO have a sleep dictator, when I watch my friend's dogs. The little one, aka "The Diva" goes to bed when my friend does, or at least goes to the bedroom as my friend usually watches tv there as her DH is in the LR. And gets up on the bed to snuggle. When I'm there, I'm up later than my friend, plus since its just me, I prefer to stay in the LR until I'm actually ready to sleep.
So when the diva thinks its time for me to go to bed, she will whine, whimper, and generally be a pest, and any time I get up, she runs for the bedroom, only to be disappointed I'm heading for the kitchen, which is the other way! And then gives me the stink eye because I'm not conforming to HER schedule. I'll be there this weekend so I'm sure she'll be up to her old tricks!
