Yep
I had that too. Good friend talked with him once.... then never again. While it is true that some people just do not give a damn, it is also possible that they just do not know how to deal with this and how to behave. So they avoid you (like you have the plague..) and then because they avoided you they reach a point when it becomes acutely embarrassing. On the other hand other people surprise you and more than fill the "void".
