Perceptions

A brief while ago, Douglas entered the room with two cards in his hand, face down. He went over to Sarah and gave her the top card saying,"Mommy this card is you....

He then gave me the next card. Looking into my eye, he devilishly smiled and said, "Yes, Daddy, this card is you." So, How do you think he did?

Perceptive angelic clownfish...isn't he???
