a child's honesty

So we were at Value World yesterday (with a 50% of coupon from Nuvo!!). Jack asks, 'Mommy, what's that man doing?' I asked, 'What man?' Jack responds as only a child can, 'That brown man.' Uhhhh, I wasn't sure how to respond, but I just said he was looking at sport coats, just like we were. I suppose his skin IS a brown shade. It's situations like this where I freak out and would like to consult someone's opinion of how to handle it. I think I did okay, and I am mentally preparing myself for future phrases like this that truly reflect a child's honesty.
