I would say that if you are bothered by this behavior then you should take a good close look at it. Maybe what you really wish you could do is stay in contact with these people from your past that you once cared for very much but you don't have the courage to take the first steps toward communication because you don't know how they feel? Just a thought. Bottom line, any behavior that bothers you probably deserves a closer look to make sure your motivations are pure because there is a reason you are bothered. Maybe you are trying to tell yourself something whether its good or not so good
