Adrian is in love with magic these days and likes to perform magic tricks to people frequently. One day last week he was holding a card in front of me. Actually those are 2 cards stuck to each other back to back.
Adrian: Ok, see this card? Try to remember this card.
Me: Adrian, did you stick 2 cards together? (My concern is, he opened a new deck of cards and ruined 2 cards.)
Adrian: You're supposed to remember the card and then I will tell you that the card has magically changed.
Me: Son, but that's a new deck of cards, we won't be able to play with them anymore, 2 cards are gone!
Adrian: That's ok, I still have 50 of them.
