Wish Upon A Star

Our kids always say "I wish" this or "I wish" that. Sometimes I get frustrated when it involes something I find to be a little greedy. For instance, if we have just bought a toy and they "wish" they had the other toy even though they asked for the one we got.
In the morning, at breakfast, they often wish for things. They all "wish" we had a puppy. I wish they knew how much work a puppy is!
