Do me a favor... Stand up, walk to wherever the nearest window is, and just look outside. You may not know this, but there's an entire planets-worth of summers, friends, sunsets, street lamps, songs, late nights, great films, and night skies waiting for you. Your life is as amazing as you want it to be, but first, you have to let it be that way.
Because of a friend, life is a little stronger, fuller, more gracious thing for the friend's existence, whether he be near or far. If the friend is close at hand, that is best; but if he is far away he still is there to think of, to wonder about, to hear from, to write to, to share life and experience with, to serve, to honor, to admire, to love.
