I am sure that this message has lost it's target. If it is not we can not see it at the shore... If we posit it at the first decision then there are some condition to think: - what is the feeling of the sender; he / she will not going to get the answer. So he / she would think that he/ she is rejected... - What will happen to delivery person, if he / she can not receive any message from the one who he / she expect...So he / She would think that he /she is betrayed... ... If there is a message in the bottle it must come form a mysterious person who can not reach to the delivery person in normal ways...Maybe it is coming from Robinson Crusoe who can not have an internet connection on his forlorn island even if he had is Iphone in his pocket...lol..
