If you do not change your direction you will end up where you are headed.
The captain of a battleship has just been informed by a lookout that a light has been spied dead ahead through the fog in the distance. The captain orders a signal sent by flashing light. “We are on a collision course, advise you alter course 30 degree port.”
The signal is straight away returned, “Advisable for you to change course 30 degrees starboard.”
The captain ordered his communications officer to send back, “I’m a captain. You had better change course 30 degrees port immediately.”
“I’m a seaman second class,” came the reply. “You had better change course 30 degrees starboard.”
Now extremely irked the captain spit out, “I’m a battleship. Change course 30 degrees port now.”
Back came the flashing light. “I’m a light house.”
