Sorry that this story is quite cryptic.

Maybe this will help make it clearer.
Long time ago, a man was walking along a beach. He has a friend that only he can see and hear.
When he reviews his walk on the beach, he sees two set of footprints, his own and his friend's. However, during parts of the walk when he faced some troubles, he only sees one set of footprints.
He suspects that his friend abandoned him during times of need, but his friend insists that he was the one who carried the man on his shoulders.
The man was confused because he didn't remember his friend carrying him at all. But he was about to accept this answer, when suddenly a bear appeared and walked along the beach.
The man saw that the bear's footprint was deep because it was heavier. He saw that the waves could erase the footprints.
He suddenly realized that his friend could not have carried him because the footprints were too shallow for the weight of two people. He also realized that his friend could easily abandon him by walking nearer the sea, so that the friend's footprints get washed away, so only one set remains.
I apologise for the heavy use of metaphors in this story.
