As I type, my cat is staring at me with her paws tucked under her and an expression of distaste because I spent most of the weekend away, again. I think I've had that same expression on my face when I've had a dog that insisted on jumping the fence and running around the neighborhood rolling in smelly treats.
Later, she'll sit on my chest at 4am, stare at me, smell my breath to see if I snuck any treats in the middle of the night, and wait for me to wake up and feed her. I feel so owned :)
