Relative round the corner

I was adopted as a 6 week old baby and grew up happily in a small town with my adoptive parents. I knew nothing of my "real" background and, as a child, really wasn't all that interested. At 18, I secured a place at Edinburgh University to study Biology . I suppose that approaching adult gave me more motivaion to find out a bit more about my birth mother so, in my third year, I made my way to Register House and obtained a copy of my full birth certificate which listed my mother's name and address at that time which was a tiny village on the far west coast of Scotland. I wrote a brief letter and posted it off. Several weeks later I had a phone call from my birth mother. She had moved away from the address I had written to her at which was her parents' home. She was obviously surprised to receive my letter but her emotions at re-discovering her child were compounded by the extraordinary coincidence that she now lived in the neighbouring street to my student flat and worked at the University as secretary to my director of studies. I still find it extraordinary that, having applied to several Universities, I ended up at the same one and with the same DoS as she worked for especially as she and I originated from opposite ends of that country and had moved to the exact same neighbourhood completely independently.
