Depth Perception

Do you ever wonder if the friendships that you have are born out of convenience? If it were a difficult to stay in touch, would both parties be willing to endure that?......is it worth it? I think that we all have those people that we see so often that we become friends simply because we are present in each other's lives consistently. Case and point, high school; you see the same people everyday for four years, but after you graduate, it is no longer easy to stay in touch with those people; so they have reunions to keep everyone up to speed. Sure some people stay close friends outside of high school or college but for the most part people lose contact with them. At present I find myself wondering about the friends that I have now. If it was no longer simple would the friends that I consider to be close work to stay in touch with me as I do the same with them? Or would I find out through the fire of trial that it was a friendship based on convenience? How deep or shallow does the river of friendship run? People talk all the time about meeting someone half way. I'll do for you what you do for me. Though one would only ever ask someone to meet them half way, you can't help but wonder how far they would be willing to go to keep the friendship. I understand that beating on a dead horse is a lost cause and no one wants to be the only one trying to keep a friendship alive..... it's like trying to teeter-totter solo; it just doesn't work. I guess that there are just things that come up that make you wonder...
