Same pupil, different location

I studied Spanish at Nottingham University starting in 1962. Before my final year, I received a grant from the Spanish Foreign Ministry to spend 9 months living in a hall of residence at Oviedo University, which is in Asturias (NW Spain). I gave English classes in the hall to a small group of Spanish students and a lecturer at the university. His name was Toni Coto. Toni and I got on well but did not keep in touch after I left. After graduating, i went to work for Esso Petroleum in London, spending an initial 2 years as an economic analyst in the Marine Planning department. Then, a vacancy arose in the small Pipeline Planning department. It was agreed that I would overlap with the departing analyst to pick up the project. As he had a single office, I was assigned to a spare office for two weeks. Also in the office was a temp adding up figures on an adding machine (primitive times). Of course we chatted and it turned out that he was temping in London (near his parents' home) during the summer. For the academic year, he taught English at an Academy of English in Tarragona, in Eastern Spain. It turned out that one of his students was Toni Coto and he had enough information to confirmation it was the same lecturer, who had switched universities. It was quite a coincidence that we had taught the same man several years apart and on opposite sides of Spain. But in addition we would certainly not have met each other except for my two-week overlap in Pipeline Planning and the spare office being available nearby and the company his agency chose to send him to.
