Some of my classes don’t have a seating chart and some of my classes are assigned to a table. No one has a required “spot” but everyone sits in the exact same place every day. If someone takes their spot, woe unto the intruder.
It’s the same way at my house. Mom has a spot. Dad has a spot. Oldest child had a spot until the dogs came. Now the boys are in a power struggle to claim their own “spots” in the living room.
Percy wants to sit next to me, always, so his spot is the middle of the couch. Drake and Haas like to try to sneak in when Percy isn’t looking and they generally get about 3 minutes before Admiral Jealousy finds a way to move the competition. Sometimes it is with the theft of a favorite toy, sometimes it is wedging a shoulder in and pushing, sometimes it is causing enough trouble that all of them get kicked outside. With any of those methods, no one else is in his spot.

The new boys are still in a “spot” struggle. They are vying for Oldest Child’s place on the big couch. Oldest child doesn’t deign participate and often resides in teen cave so it isn’t a three way competition.
The struggle was real this weekend when Drake took 2 full minutes to circle and find the perfect relaxation position in Oldest Child’s spot. He was stretches out and happy looking. After just a short time, there is a bit of a cry and I see that giant Haas (who has a good 40 or 50 pounds on Drake) is flopped down on top of Drake while Drake squirms and fights for air and freedom. Fortunately, my littlest boy is more agile and was able to quickly get free. I don’t think this was the end of the war, though. My little shark may get his spot, yet.
The kid/dog couch has enough room for all three of those monsters.
