I have no children, but I have noticed that they really like to remove whatevers on their feet be it shoes or socks. I bet it's, because they since they can barely walk it's already awkward enough and they don't like anything inhibiting their feet.
As a man lesser inhibited by the commonality of proper attire (I live in outer-suburbia, and alone, for the most part,) clothes aren't comfortable unless they're keeping me from freezing my ass off.
As a man raised in a quiet family, I usually dislike having my bare skin exposed to the sun or the wind and I often wear turtleneck in summer. And a hat. Hats are awesome, you MUST wear one if you can.
As a man raised in a average family home, I usually enjoy wearing the attire that best suits the current state of the weather ouside while wearing lesser indoors. On occassions I wear hats depending on my current mood.
As a man raised in quite modern home in a hot provincial area, I usually wear light attire as the heat of the sun is unbearable outside and would just wear tank tops all through out the day. Even in an air conditioned house I still prefer wearing as light a clothing as possible as the contrast between hot weather outside and cool air inside is quite refreshing.
