So, I Don't Get This

Haiku and Taki like to sit on the office chairs in the computer room.  And tonight, when I went into the computer room to do some computering, they were each in an office chair.  So, I moved the wireless laptop to a TV tray and sat on the lounge chair. No big deal.  Taki jumped down to the floor, and kept nattering at Haiku in her office chair.  Haiku finally had enough, and left. Taki jumped into the chair in which Haiku had been sleeping, and ate from the cat food dish, then returned to the floor. Haiku returned, and jumped on the chair that Taki had been using. So I returned to the chair at the computer desk where Haiku had been originally, and plugged the laptop in again, for charging and printing purposes.  Musical cat chairs.
