Friendship as a Development

We have talked a lot about the different categories of friendships and it made me start to analyze my relationships with my friends. I took a look at how they all began and why I've remained friends with some people while others have drifted away to mere acquaintances. It got me thinking that, although there are friendships like we discussed in class (utility, pleasure, true), a friendship is a constantly developing idea, even with our closest friends. In my personal experience many of my closest friends have at one point been some of the people that I tried to avoid at all costs. We have discussed that point and came to the conclusion that as we age (not necessarily in years but in maturity) our interests change and certain behavior that repelled us before is no longer present and therefore the differences have resolved. Even now one of my close friends is going through a phase where he is distant from the group and even though I still consider him a close friend I wouldn't necessarily place him into any of the three groups. Neither of us get any utility out of the relationship and though we can have fun times in a group I wouldn't call it purely a friendship of pleasure, he has simply drifted away for the time being and so it isn't a true friendship either. In conclusion, I think some friends don't fit in to the groups we have talked about in class and each case varies based on many criteria.
