I know what you mean. My eldest is in a football team. I don't mind the game to watch but I am less enamoured with the people it seems to attract. Football tournaments in particular seem to bring out the worst in people. So far I've had one blazing row with a coach at a tournament. Football seems to attract a lot of dads who are living their own dream through their children.
It does keep him fit though, teaches him the value of teamwork and he gets a lot out of it. Fortunately or unfortunately, he is quite good, not academy good but a solid player, so I'm stuck with football for a while longer. I just have to continue to ignore the muppets and he already knows how to recognise them anyway.
