The High Jump

I have two six foot tall bookcases in "the office."  One is some four feet diagonal from the printer, and about two feet higher...Haiku likes to jump from the printer to the bookcase, then to the other bookcase, down to the desk, and onto the floor...This is not a regular occurrence, but happens sometimes.  Usually when there has been some other disturbance... Tonight, Sake was irritated and took it out on Haiku.  Although they both ended up in the garage at the same time, there seems to be some tension between them, still.  So, I think the jumping is  a release for Haiku, and demonstrates her prowess.
