Call Me Courageous 

Gun is a child who is very timid and geeky ..
One time he and his friends went forestry at night to camp there,,
when a friend suggested it to test their courage still on the edge of the waterfall, was the last gun,,,
it was time turn gun,,,
the sound of roaring noise sounded wolf gun up and started to walk backwards until falling into a waterfall slip, with his friends soon cometh by hearing a loud bang,,,
"I'm here" said gun
"Why are you there?"
"I was seeing a ghost down here and trying to catch it for you but unfortunately he just goes"
