Have you ever had someone in your life who says that are going to do something and just never seems to keep their word? Maybe you have a best friend who is a great friend overall, but just seems to fall short in the following through department. You can choose to continue your friendship and accept that they just are absent minded or inconsiderate, or you can choose to not have that person in your life anymore.  I am very much a believer in accepting people for who they are, but there are limits.
