Meetings with an old friend after many years

Last July I took part in the first concert of the 2011 Proms season at the Albert Hall. Because of the number of performers in the concert the men's dressing room was front of house, below ground at the level of the entrances to the arena (where the Prommers stand). Shortly before the concert I went to the men's room next to the dressing room and met an old friend with whom I had not been in contact for at least 15 years (we are both in our mid-60s). He had only decided to attend the concert within the previous few days, and although a frequent concert-goer he had never 'prommed' before and therefore had never previously used this men's room. In November I returned from a concert at the Barbican to Waterloo by a tube route that I had not used before, because of engineering work on my usual route. As I got out of the tube train this same friend was waiting to board the train at the point on the platform where I was leaving it. In a lifetime of using the tube for travelling to school and work I had never had such an encounter before.
