It's not really weird, but, it's consistent and it's a trait unique to Finn (compared to any other pets I've known). When I leave, he runs upstairs to watch me from the window. He'll watch me get in my car and drive off. And, when I drive up, I think he knows the sound of my engine, because my mother says he always goes to the window, no matter where he's at. And, as soon as I lock my car (it makes a honking sound), he lets out a little whimper at the front door. I guess he's quirky, in that he hops around, like a rabbit or antelope or something when I come home. And, scrunches his nose up and smiles at me when I get home, too.
