Purplecapricorn posted a funny photo of a cat giving his regal stare, lying on the master bed with this caption: "I don't care if you're both in the mood, you can roll around on the floor like the lesser species you are. It's my bed and I want a nap."
It reminded me of how I allow myself to be manipulated by my cats. If I'm sitting on the couch and get up to grab a drink or do anything quickly during a commercial break, I often will find one of the cats sitting in the exact spot I just vacated. I won't move them because I feel it's rude. They're family members and they just claimed their seat when I left. I have to choose another spot now.
My husband thinks it's ridiculous to allow an animal to dictate their will over a human. He'll move them off of any chair or couch when he comes to sit down. It doesn't matter if they've been on the chair for hours. If he wants to sit down, they have to go! It's the same way in bed. If they're in his way in bed, out they go!
