I cabled to England, and when, three days later, nothing had happened, I tried to telephone. The call had to be booked twenty-four hours in advance. On the first day the line was out of order; on the second the exchange was closed for a religious holiday. On the third day there was another breakdown. My friend left, and I arranged to meet him in a week’s time. Five days later, my mail arrived.

Explanation:

 

The author attempted a telegraph connection to England, but when there was no answer, he tried a call that required reservations a day in advance. Due to a holiday and technical difficulties, he was unable to contact them for an additional three days. After his companion finally left, they both agreed to meet in a week. Five more days passed until his mail finally came.
