I will never forget 'The History Boys': there was a character in it, James Lockwood, history student, who became an army officer and died aged 28. I have a son, same name, same age when I saw the film, also then an army reservist officer, who was 28, and a history graduate. I was dead relieved when he turned 29! The part was played by a lad with my Mum's maiden name.
So many coincidences. Of course, it was set in West Yorkshire where that son was born.
I wrote an email to Alan Bennett about the coincidence and got a lovely postcard back.
