We were waiting out a thunder storm in the Institute hall. A lightning flashed. I counted to six when the thunder rolled. I multiplied six by 300, it made 1800. Well, the lightning had struck very close by, I thought. Two girls were standing beside me. Suddenly I asked them: “Do you know how to tell the distance to the lightning?” They smiled condescendingly: “We have finished school and need this no more”. I didn’t know what to say to them.
“Waiting out the thunderstorm”.
