Okay..private Joke...

One night a captain sets the anchor on his vessel right off the beach near a lighthouse. He is going to bed and asks the deckhand to stand watch. Tells the deckhand, " If we start drifting away from this lighthouse, wake me immediately!' The deckhand says okay and the captain hits the rack.
Next morning the captain gets up to relieve the deckhand and cant see the lighthouse anywhere. He is very distressed and asks the deckhand " Where is the lighthouse? Why didnt you wake me when we drifted off?" The deckhand replied " Oh No captain, I watched that anchor line all night it didnt move, the lighthouse just cranked up and hauled ass to town".......

Perception..is it reality?
