Not a problem.
Born early 60's parents not in to football. My mum had a soft spot for Man u because of the Munich thing. So being easily influenced by Mummy I liked them.
As i recall my best mate (who still is by the way) liked Leeds but i didnt want them. You have to remember I live in S25 and we didnt have a car, so a trip to any town seemed to be the nearest (worksop) was a big event and on a bus.One day in school after a kids type talk another friend suggested i supported a team from a local area, I picked up a map and looked where i lived and where i was near to. We used to get Sheffield Morning Telegraph paper, so i read about local teams and made my choice.
So you see a choice made on such a basis maybe is even better than an inherited choice. Sorry if that maybe a little controversial.
