Some years ago, when I worked in London, a friend gave me two tickets to the ballet at one of the theatres. He was well connected, and these were good seats. He could not go so he gave me the tickets.
I could have thrown them in the drawer and forgot all about them. I could always tell him I enjoyed the show. Or I could have given the tickets to that beggar I saw sitting on the ground on my way to the railway station. I gave him some money instead.
