A "hairy" problem?!

3 times, by 3 different people, at 3 different places, my cute/handsome little Kamden has been called a her :( People, do you really think a little girl looks like that? Have you seen a girl with skateboard shoes, not wearing pink, no earrings/bows or other girly junk, and wearing a green and blue jacket?! Just because he does not have a clean cut haircut, does not mean HE is a girl! I have been debating cutting his hair for a while, but his hair is part of his personality. He is my surfer, beach bum (yes, I am aware we are no where near the beach), he is a little imp, a happy, mischievous, free spirit - his hair fits his personality, and he is NOT A GIRL! I don't know what to do! It is fun to make people feel dumb for being unobservant (I know, not nice to say - but I never claimed to be nice), but is his hair really that questionable???
