When I was 6 I used to like a specific type of candy. My mother used to buy them in 12-piece sets, they were cheaper.
She'd hide the box somewhere in the house and give me one each day, I always managed to find it.
One day I told her to stop hiding the it because I'll always find it. Next day she challenged me to find the box, and she said if I don't find the box she'll never buy me the same candy ever.
For one week I wasn't able to find it, the I realized, there's no box.
