It could be one incident, one sentence, a look, a call unanswered, something you did or didn't do, and there goes the best friendship you ever had. There went the trust that took years to create. All it took was one moment in time gone wrong. Your life takes a turn and it's never the same, something is always missing. Sadly you can't turn back time. You may get a second chance if you're lucky, but most are not. Definitely do your best to make amends for any wrong done on your part even if you are not granted forgiveness. Forgiveness comes from within you. Just realize that some people are placed in your life temporarily to help you grow and others will stay for the long haul to grow old alongside you. We all have our own path to take in this world and not everyone will be able to take it with you. Appreciate those that are in your life now and thank those that have always been there.
