Just a season

I know people are in your life for a reason even if it is just for a season. But how do we know which one and when do we find out? when we meet? along the way? or at the end? There are times when they've fulfilled their reason then the signal gets crossed and we try to extend them for another season. Maybe they weren't meant to become a permanent friend. But you keep them around 'cause you don't want to let go. Things start to fall apart and you realize all good things must come to an end, the seasons must change and you can no longer be friends.  Out of your life, just as quick as they came. From the experience I hope that you both gain.....wisdom.....so their season was not in vain.
