What cheap is to a six year old

This morning on my way to work!  My son Elias was telling me all the things he wants from Santa for Christmas. He went on and on in his cute little voice on all the things he wants. One of the things he told me he wants is a remote controlled car. After he told me that he goes its cheap mommy its only 30 bucks. I laughed and was like OH Elias if you only knew what cheap is. Its cute to know 30 bucks is cheap in the mind of a six year old.
