Grace goes through different moods. I can trigger these different moods. She can be happy and ready to play; in that case I can pick her up over my head and throw her on the couch. Grace can also be easily irritated occasionally; also this is rare and it is funny when it happens. It is not a natural state, per say.  She enters it for one purpose and it usually works — to make everyone else think that I am teasing her, which I’m not, usually.  I think this shows a high level of intelligence through this complex manipulation that I think she is fully aware of.  She uses this to get me in trouble.  Sometimes when I’m not even in the same room.
