My husband and I were at a public swimming pool when the people around us started staring into the sky. A small plane was emitting smoke in the form of letters. As we watched, the pilot spelled out the letters: “I L-O-V-E.” People began speculating: Maybe it was to be a marriage proposal. Perhaps a romantic man is standing nearby on a balcony with his girlfriend and will soon pop the Will-you-marry-me? question.
