Nature vs Nurture

We have this discussion a lot in our household. What skills, traits, or behaviors are you born with, compared to what you learn from those around you.

I had bought these teeny, tiny ice cream cones for Noah's party, but didn't end up using them. Dan decided to get them out the other night and fixed up one for Jack. Both of us were shocked that he knew right away what to do with it. Which makes me wonder, are you born with the knowledge of how an Ice Cream Cone should be eaten?

Here are a few pictures of him going at it:
He really enjoyed it and didn't make that big of a mess with it. I'm surprised the cold didn't bother him.
