I don't get a chance to brag about Hannah very much because she is not known as Miss Cooperative, but there is one thing that she does which I think is quite bright. She has a tendency to take certain things of mine and run off with them, depositing them who knows where...namely my slippers and my gloves. I will generally run up on one slipper for example in the living room. I will show it to her and tell her to "go find the other one" and off she will go. She will chase around the house and pretty soon she will come back with the mate to my slipper. She will do thing if I find one of my gloves and tell her to go find the other one.
