Missy Annabelle is particularly frisky this afternoon. I received three shipments today, two from Amazon and one from Chewy, which was a lot of cat food. I unpacked everything in the hall and when I carried the first load of contents into the apartment, she darted into the hall. I figured, fine, I've got enough to deal with at the moment. She didn't go running to the fourth floor, just ran around the third, sniffing doors, checking out Judy's shopping cart while I carried things into the apartment. When she got bored, she came in with me.
