Crazy Dancing Baby vs. The Baby Who Is NOT Amused

There are many different personality types in this world but let me tell you, nothing shows exactly how true that is like this video does. A baby girl dances and shakes her head back and forth (with serious rock n' roll intent) while listening to music. Not only is she completely rocking out without a care in the world, she stops to have a smile at the camera and to have a look at her brother. Her brother, on the other hand, is completely serious and so far from amused with his sister's dance dance vibes. I mean seriously, check out that somewhat cold stare her brother is sending her way.

Could this be an early sibling rivalry? Or is it simply, a brother and sister who show expression in a VERY different way? Either way, we are going to file this one under CUTENESS OVERLOAD.
