Monster Trucks or The Nutcracker?

The Nutcracker is an 1892 two-act Russian ballet performed by countless ballet companies, primarily during the Christmas season.  I remember being exposed to it somewhere along the way, but also remember not being very interested.  We’re not sure where he heard about it but my 3 1/2 year-old great-grandson, Crawford, asked if I had a video of “The Nutcracker.” I googled and found a link to something that looked like it might please him. (Understand, I am not an expert on Nutcracker videos.) He watched it patiently for a few minutes. Just when I had begun to think he might have an interest in something classical, he blurted out, “Can we switch it to monster trucks?” “I’m sorry, Lord.  I know the Bible says, ‘Train up a child in the way he should go, and when he is old, he will not depart from it’ (Proverbs 22:6), and as You know, I did my best with my kids and grandkids, but apparently, I have very little influence on this great-grandson.” Can interest in monster trucks possibly come through DNA?
