Phrasing the words of a brave captain,'We voyaged through the never ending seas. The funny incident was when two of my sailors were standing on the opposite sides of the ship. One of the sailor was looking on the west and the other at east. But at that very time, they could see each other clearly as well.'
How can that be possible?
This can be possible if they were looking across the deck at each other and were not looking at the sea.
