Yes, I recall that when I was four years old my mother and I came home from shopping and my mother told me not to tell my Dad that we got him some socks for Christmas. So when my Dad got home I said something sort of like, "Guess what! I'm not supposed to tell you that I got you socks for Christmas!" Of course I was only four or five years old at the time. I'm older now and not so prone to reveal my own personal secrets. But if you already knew that, it is probably not a secret anyway.
