Sir C, The Lord of the Lords!

So one midweek night, at about 8 as I was calling it a day at work, I received a call on my mobile phone from an vaguely familiar voice from a unknown land line. He went on rattling with the usual pleasantries. As social etiquette dictates, I returned the kind pleasantries until he asked whether I could recognise who he was. I plainly told him no and guess what - I have not seen him in 10 years! (and he expected me to recognise his voice out of nowhere!
Anyway, he is nice guy who does not mean any harm to anyone. Quite an interesting character actually...
I first came to know of his acquaintance about 20 years ago. By then, he was a senior doctor with years of experience supervising interns in his own unique way. In his mid 40s then, he was a bachelor, a laid back character who was contended with life caring for his brothers and sisters as well as any sick and poor patient who would walk through the department door. He did not give much credence to post graduate studies. His parents had pass on quite earlier on and he had to shoulder the daunting task of being the head of the family to his much younger siblings. One of the sibling was mentally challenged.
C, was an amiable old chap much liked by his contemporaries, was fondly 'knighted' by them as Sir C. During one of his call days, he had to perform as many as 3 Lords' procedure for thrombosed piles. This prompted some to also refer to his as Lord C.
A year after working together, I moved on to another department but still kept in contact. About 5 years ago, he retired from public service. He is supplementing his income by doing locum work. He is now married with a son. Till date, he does not carry a mobile phone. Anyone meaning to contact him has to do so the old fashion way - leave a message in his home and he would return call. (No FB or Twitter accounts, naturally) -but he is happy. I wonder what car is he driving these days. I remember him in his old Toyota LE 1.3.
