Dear Mr. Dad: I came home a little earlier than usual, walked into my bedroom, and saw my 6-year-old son sitting in front of the mirror, wearing one of my short dresses, heels, and applying mascara. He didn't notice me at first because he was so busy talking to himself in the mirror. But as soon as he did, he scooted past me as fast as he could and went straight to his room. I'm worried and would like to talk with him about this, but he's been avoiding me for days. What should I do?
