The Enemy of My Enemy is My Friend... Sort of
Neither Sake nor Haiku are very happy about having TLK in the house. Haiku, being so much more mellow, is more accepting. Sake is just mean and bitter. Haiku is breaking the rules, and more and more, exerting her place, and sitting where Sake is: both on the sofa back, both in the open window in my bedroom (each on their own side), both on the bed at the same time, and not separated by as much bed as possible.
So, either Haiku thinks the enemy of my enemy is my friend, or, since she is no longer "low man on the totem pole" she has more confidence that allows her to exert herself.
