Everywhere in life we have rules, even in our most laid back recreation.
If you and your buddies go out to have a few beers and shoot some pool, and your buddy scratches, you are going to hold him to the rule that says its now your turn. Did you still not have fun that night? If you and your buddies are in a saturday softball league and the other team wants 4 outs, you are going to point to the rule that there are only 3 outs per inning. Was that no fun?
If you and your buddies show up at the park to play a little 3 on 3 pick up basketball and your buddy travels, you are going to call him on it and possesion goes to you.Is your buddy going to take his ball and go home because it's not fun anymore? If you are teaching your child to play checkers and they do an incorrect move, you tell them they can't do that and you continue the game.You still had fun playing and teaching checkers to your child.
Rules are put in place so that controversy does not happen. Controversy cannot happen if there is a rule in place to prevent it. Controversy happens when people ask to circumvent the rules.
