<span><em>An old scientist whom everybody in</em>
<em>
England knows very well is travelling by train. The</em>
<em>
ticket-collector makes his round. When he comes to the scientist</em>
<em>
and asks him for the ticket, an old man begins to look </em></span>
<span><span><span><em>though</em></span><em>
it in his pockets, in his bag and suitcase, but cannot,</em>
<em>
find it anywhere.</em></span>
<span><em>" It </em><span><em>doesn't matter", says the ticket collector, who knows the scientist very </em>
<em>
good." There, is no hurry. I can come again </em>
<em>
on the next station". "Oh! But I can find</em>
<em>
it", says the old man helplessly. "I want to know</em>
<em>
where I am going".</em></span></span></span>
