Another interesting question is this, as a father would you force it on your child to also fan the same club you're a fan to, or you will allow him be himself to fan any club of his choice even if it's your most rival club of all times.
Of course, as a father, I completely respect my child's preferences and choices. You can't force him to like your football team, while you also have no reason to like your child's football team, right? Imagine if your father did the same thing to you, how would you feel? There will certainly be resistance and dislike. Football is a hobby, and if it is a hobby, there is no right or wrong and there should be no compulsion. Each team has its own characteristics that make us love them. I find it more interesting when my child likes the opposing team, through which we will be able to argue more, thereby discovering more interesting things and points that our team needs to improve. There must be conflict for there to be development.
