Most of my boys are especially good at dancing. Probably because we have danced with them since they were born. Eli, for example, is a good dancer when he wants to be. It doesn't come naturally for him, but he still can dance when he tries. Matthias, on the other hand, is naturally a world class dancer.
Here is my proof. Eli obviously wasn't in the mood for dancing so he defaulted to his normal craziness. Matthias is always in the mood to dance.
