My dad was a City fan, season ticket holder in the 70's before family meant he couldn't afford it any more. His dad was at City as a youth player, a goalkeeper. Never got to play for the club as this was in the late 1930's so the Second World War came along, he was called up, and he ended up with a hole in his skull due to a shrapnel injury (used to have a big dint in his forehead which, as a kid, I found fascinating!). Unsurprisingly it was American friendly fire that got him! Anyway, I simply followed the family tradition! My younger brother, on the other hand, decided he didn't want to support the same team as my dad and I, so became a United fan. Fairly stereotypically my dad and I became City season ticket holders whilst my brother barely went to Old Trafford, and now lives in Australia!
