Here is my example. My ex-boyfriend, when exiting the bed, would literally push the entire mass of covers half way down the bed. How did he do this? He would leave through the top of the bed rather than through the side. If you leave from the side you can just pull back your half of the covers, but if you leave through the top you must pull the whole length down to leave more easily.
I often complained, and he was often oblivious, and self-deluded. Definition of asshole? Yes.
