To last forever friendship must always "up a level". one must learn to understand the other, to understand the changing needs. You never remain a teenager, you become men and women. Time at one's disposal lessens, and, for this reason we learn to appreciate the quality other than the quatity of the hours spent together. It doesn't mean loving less, the love never alters. It only means growing and changing together, we will always be there, one for the other and that will always be part of our thoughts. Only the maturity in accepting change without showing selfishness, will make two kindred spirits together, forever.
