It's Only Fun When...
Is the saying "It's Only Fun When It's Fun For Everyone" a matter of truth, etiquette or doctrination of culture?
It depends upon the situation and who you are referring to. The statement is idealistic. In some situations it can be based on truth. In many cases I am sure it is said out of etiquette or political correctness. As for doctrination of culture -- that would depend upon the culture in which one is living. I can truly only judge whether I am having fun myself. Each person in the group would need to make that same decision. The statement would be more true if I were to organizer of the activity. When I have put time and effort into an activity I am going to enjoy it more if I believe everyone is having fun.
I agree that the statement is idealistic.
In most cases whether someone is having fun or not depends on quite a few variables, and on top of that how each person defines the word fun, and what events or things each person lets affect how much fun they are having. Being able to satisfy all of these variables in a given situation so one can finally say that everyone is having fun seems a bit of a far cry. Therefore...idealistic.
