On the way down from Central Park each time, Shio and Elsie will sit and fight for the middle space in the back seat between my friend and I. They are like two little kids, I swear. No long road trips with them... ever.
Here's a video fo the two of them fighting while sitting in the seat.
In this video, Shio is on the floor while Elsie is still perched on the seat. Shio has lost the battle, but not the fight (yet).
