The right side of the couch is where I usually park myself. There’s an indentation shaped like my butt to prove it. I have a recliner but I don’t sit on it that much.
On the couch in the exact middle of the sweet spot of the TV and speakers.
Right side of the sectional, the side that allows me to put my feet up on the “L.” And, yes, I do fall somewhere between Sheldon Cooper and Archie Bunker if someone’s in my spot. Usually, if a kid or spouse is there, I’ll look at them and say “What is this?!” and they sigh and roll their eyes and then move.
My wife’s spot is the love seat, mine is left end of the sofa, the Firebug’s got the right end of the sofa.
