Thank you for the answer.
Once when I was about 10 or 11 years old.I was in a favourite forest valley which to-day is a housing project.My cousin's and I played there for years.But on that day I couldn't fine my cousin so I went into the forest to a fallen log.On which we,my cousin and I had sat on. On many previous occasion's.I began banging on the log and discovered it's acoustic value and I banged on it for some time.
After which I returned to my cousin's house and found him there. We where sitting on the curb.When; I heard, a kind of chanting, by a old man. I turned to my cousin and asked." do you hear that?".
He turned to me and said," You are hearing voices again.".
Both my cousin and I never return to that valley again.As we I suppose we left childhood games behind us.
As I write this the font changed again part way through this story.
