Funny story when I was in the UK two people born and brought up in the country came to my desk talking about a third person. I honestly thought they were speaking about two different people. While I was totally confused they seems to perfectly at peace pronouncing same name so differently. It was a classic Shawn vs Sean moment[1]. This feels weird personally because in my mother language Hindi this is nearly impossible. Each alphabet have a distinct sound. You just pronounce a word in 2 different manners.
