Long before we knew Alexis would be Alexis, before we knew she was even a she, there was a phase where her code name was "Thumper." It wasn't so much because she liked to use my bladder as a bongo (although, she did), but more because her feet were constantly in motion. Kick...kick...kick. Stomp. Kick. Thump. Stomp....Stomp...Stomp. KICK! THUMP!
In retrospect, I suppose that was just some early dance practice. She has been preparing for a career as a Rockette since long before she was born, and still continues to do so every single day.
