Mr. Robinson had to travel somewhere on business and as he was in a hurry, he decided to go by air. He liked to sit beside a window when he was flying. So, when he got on to the plane, he looked for a window seat. He found all of them had already been taken except one. There was a soldier sitting in the seat beside this one and Mr. Robinson was happy that he had not taken the one by the window; but, anyhow, he at once went towards it. When he reached it, however, he saw there was a notice on it. It was written in ink and said “This seat is reserved for proper load balance. Thank you.” Mr. Robinson had never seen such a notice in a plane before, but he thought that the plane must be carrying something heavy in its baggage room which made it necessary to have the passengers properly balanced, so he walked on and found another empty seat, not beside a window, to sit in. Then, when the plane was quite full, a very beautiful girl stepped into the plane. The soldier quickly took the notice off the seat beside him and in this way succeeded in having the girl beside him during the whole trip.
