Some weeks ago I sought to make contact with two old friends I had known in the early 1990s. I had not spoken to either one since about 1993. This kind of thing is always an uncertain proposition, as you can never really be sure how a person has changed over the years. Sometimes you may find that the person has little enthusiasm for reconnecting; in some cases old friends may have changed beyond all recognition. But in spite of this I was not deterred: my experiences in doing this sort of thing have always been very good.
