The dilemma
A father who lived in the UK had a son studying at a university in the US. During his term break, the father wanted his son to come and attend a big family wedding in the UK. Since airline tickets are very expensive, the father decided to buy the tickets for him.
First, the father wrote a letter saying that he knew how expensive the tickets were so he would purchase the tickets and post them to his son. He instructed the son not to buy the tickets himself (he couldn’t afford it anyway!), but wait for his father’s correspondence. Then he sent him another letter saying that he was arranging the tickets and that they would be enclosed in the next letter. ‘Wait for that letter’, wrote the father, ‘and then use those tickets to come and see me.’ When the third letter arrived, the son opened it and found the promised tickets!
The son was happy and excited about his trip to the UK, but then saw another letter arrive in the post. This fourth letter was not written in the father’s handwriting, but had his name signed at the bottom. The letter told the son to throw away the tickets and instead to take flying lessons and build an airplane so he could fly to the UK and see his father. Now, what do you think the son should do? Should he throw away the first three letters and obey the fourth?
