I maintain the theory that my siblings are fast because of all the chasing of them I do from a young age. I don't hold back, so they have to learn how to run fast :) hahaha.
Hahah, for some reason whenever I get around little kids I just go into instant Crazy Kat mode. Running, games, racing, carrying, forts, etc. It’s the product of being the favorite cousin. 2-10 year olds are my specialty.
Anyway, cheers to you as well!
