This is not news.
Studies, stories, and certain stereotypes surround the concept of inter-species look-a-likes. Consensus has long been that married couples begin to look alike, and Rachel Toor combined both concepts by pointing out how her pets resembled her husbands and lovers in The Pig and I, cleverly capitalizing on the theory.
A couple of days ago one of my clearance fish died and the survivor was listless. After being frustrated with PetsMart for telling me plants would be in Wednesday... no, Tuesday... no, Monday, and not having plants for three weeks I bought plants and a few small fish (elsewhere) to keep my clearance fish company. As soon as I got the new fish in there he started swimming around them, but curiously didn't join their mini school. It was enough company just to know they were in the tank with him, and he stayed nearby, keeping a tiny distance. Most of the time I know that my friends are nearby and I can see them any time I want to, and contentedly live alone the rest of the time. However, this weekend it seems most of my friends are gone: off on spring break, on a camping trip, or generally too busy on weekends to get together. I feel kind of like my clearance fish felt before he got companions.*
No, we just don't like him.
Chloe, on the other hand, is both very much like me and very much not. Her tolerance for company is painfully limited; she prefers solitude, but when she wants attention she's rather enjoyable. You don't go to her, she comes to you. Of course, sometimes she's plain crazy and will attack your ankle simply for walking past her. Lucky she's cute enough to get away with almost anything, except standing in the potted plants, which happens to be her new favorite flavor or mischief.
Sure, she's cute now.
*EDIT: Clearance fish #2 died Sunday. Figures.
