One of my friends and I used to believe in ghosts. Our other friends would say that there are no such things. But we always maintained that if you believe that God exists, ghosts do as well. We tried to scare our friends, but they became tired of it.

A few days later, my friend and I were playing with cardboard boxes. The boxes were so big that both of us could sit in it comfortably and we would chat. Then we heard a strange sound. We were scared and convinced it was a ghost. We came outside screaming, but later realised that it was our friends who had made the noise. They had planned to scare us and prove that there were no ghosts. Sure enough, from that day on, I stopped believing in ghosts.
