I'm a Man United fan who isn't from Manchester, so I fit the stereotype clearly. But it doesn't bother me.
I've spent most of my childhood growing up in Ipswich, until I was 14 where I moved to Northern Ireland and live here still.
I don't know why I supported Man Utd, just did, not because they had just won the title, mainly because they were practically everywhere, magazines, videos, shops etc. So I grew to like them from that for one reason or another. I was only 7.
It was a very common trend for people to support Man U from a young age, and then change to support Ipswich as they got older. I didn't, so in that regard I feel as if I'm unique, and only wanted to support one team ever in the first place. I go over to see them play regularly, around 5-10 times a season since I'm a Man United member, but I don't like flying so if I was living in England still I would see them more often probably.
Hey it could be worse, I have a friend who's born and bread in Ipswich, hardly been outside of the place, and supports Everton....
