What have I done?

Cosmo is giving me a strange look. I suspect she is looking to see if I am going to put my hand in my pocket to pull out a bag of treats. Well unfortunately Cosmo is out of luck today as I was in a hurry when I went out. In such a hurry I forgot to pick up her treats. So no matter how good she is, there is going to be no reward other than to say what a good dog she is, and to give her a pat.
