Male, Female or Email?

Caleb asked me what a card with his picture on it was for. I was explaining that the company that does the school pictures sends a card with the kids photo on it. On the back is a place to fill in their info (height, weight, birthmarks, etc.) so that if they ever end up missing, you can give the card to the police and all of the information is there. I asked Caleb "Are you a male or female?" "Email." Caleb replied. "Female?" I asked. "No, email" he said stubbornly. I am so glad he knows everything!!
