What is Fun?

So while me and a good friend were walking to class, I was complaining that my ears hurt from my earrings, and my friend who is of the male category declared that if he were ever to get a body decoration or whatever one would call such things, he would get a tattoo. I agreed, but said I would never have one, because Mormon's can't. I immediately regretted that phrasing. I mean, generally people don't, but the word "can't" is so restrictive. And thats not the point. These things are made to help us respect ourselves, save us pain, and other things I probably haven't thought enough about to know. Anyways, after I had said this, my friend said "Gosh, can't you have ANY fun?!" To this I replied "Well, what do you define as 'fun?' Because I certainly don't think puncturing your skin a billion times to fill it with some kind of lame graphic is exactly a joy ride." He didn't really have much to say after that, but it got me thinking. What is fun, and do the rules, or mostly recommendations, of the church really restrict that? I don't think so. I have heard of so many people who regret the tattoos that they had gotten in their youth, because they don't look as good later in life, and also because it doesn't hold the same meaning to them now as it did at that time. So though it might be fun to show people it when you got it, is it fun later to have to wear clothes that cover it, or worry about it all the time? Is it fun to get drunk to the point of memory loss, and have people tell you about all the stuff you did later, only to find you've done something you regret? I mean, fun is able to be interpreted in so many ways, and the media portrays so many things that we members don't participate as so glamorous, but you just have to think, is this really what you want to be doing?
