People think my son is a girl because of his long hair. How would you handle it?

My son is 6 years old. We've never cut his hair. He has beautiful, blond, slightly curly hair. We leave it down sometimes or put it in a ponytail at the nape of his neck, just like dad. Of course no one thinks Dad is a girl!People often comment on my 3 beautiful daughters. Sometimes I correct them, and they get all apologetic. Then I try to reassure them it's ok, it's a common mistake, it's not a big deal, etc. Sometimes I just let it go. How would you handle it?For what it's worth, it doesn't seem to bother my son. He usually ignores it, or sometimes says that he's a boy with long hair. via /r/Parenting http://ift.tt/2wVm33L
