Communication Error

Caden and I went to Barnes and Nobles the other day to look at books. I think we both could look at children's book all day! Anyway I let him pick out a book because you can never have too many. :) We go up to pay for it and he takes a turn into the Starbucks next door. He runs to the counter and starts saying "chi chis". I try to guess what he is saying. I ask him several things and still nothing is right. Well we pay for the book and leave. He is still saying "chi chis" as we walk out the door. We are both getting frustrated because i don't know what he is saying. I ask him if he is saying cookie and he says yea. okay so he wants a cookie. It is getting close to lunch time so I drive by McDonald's on the way home to rent a movie, and I get him a cookie and some juice while we are there. He does not want the cookie after all that. He runs back to the counter and starts saying "chi chis" again. So I order a small fri. Once we get them I show him and he runs to the table and sits there and eats them all. He was talking about French fries that whole time. I guess he thought you could run up to any food counter and order French Fries. :) Well at least now I know what that word means. I have a feeling this has only just begun!
