It can all change. When younger(now 17) my son supported Man u, they had just done the triple and so were the idols of all impressionable youngsters. I soon cured this by taking him to a Saints game and he has been a passionate supporter ever since. He has a season ticket and because he is now driving he is also going to away games, his first long trip being to Cardiff.
Obviously we would all like to be playing in the premiership but this should not detract from the team that you support whatever division.
