i have always walked on the front halves of my feet, it just feels more natural, animalistic to me. i do it around the house in my socks. plus, i grew up in an atmosphere where i felt i had to be really quiet, so this tiptoeing helped. i am so good at hardly transferring weight, i could run and no one would hear me.
my mother however, has this annoying way of stomping her feet heel-first on the ground that ALWAYS sounds loud and angry to me. i guess she didn't have to grow up being quiet.
