Most of the day, Maggie stays downstairs on the couch or in front of the window in the living room. She doesn't like being in my room very much, and I'm not sure why. It bothers me, because I'd like her company.
But sometimes, usually in the afternoon, she'll come upstairs, enter my room, and make this face:
I think it means, "Hey, are you busy? If you want to play, that's fine with me."
