Getting Dirty

Lawson LOVES to play outside.  If daddy is outside, and Lawson is not, he will go to the door and cry to get out.  He also cries when we bring him inside.  I'm curious to know if this is just a boy thing, or if a little girl would get just as dirty outside playing.  This is what he ended up looking like yesterday after he played outside....of course this was when daddy was watching him.
