Just a little confused

J...h came home from school in a dizzy of excitement. "Mom can we go to the farm today after school. My teacher is going to be there for story time and so are all of my friends" I couldn't figure out what she was talking about. I explained that we were not going to the farm but to Barnes and Noble for school story night. Her eyes lit up with excitement " Yes Mom that's right we are all going to the barn!" Needless to say she was just a little confused as to why you would call a book store a barn if they didn't have any animals.
