He had never forgotten Mr.Pidgen; that walk, that vision of the Scarecrow, stood, as such childish things will, for a landmark in his history.

He came to believe that those experiences that he knew, in his own life, to be true, were true also for some others.

I daresay his theory is all wrong.
I can only say that I _know_ that they were his friends; perhaps, after all, the Scarecrow _is_ shining somewhere in golden armour.
