The older we get the more of our friendships we tend to outgrow. There are many reasons why a friendship that used to be the perfect fit has suddenly changed and it's no longer right for us in our current period of life. In addition it's a slow realization brought on by distance or change in circumstances where we gradually come to realize that what once was is no longer. We can reinvent ourselves and try new things at any time, especially in our 20s when this is not only permissible but highly encouraged by our society.
