When a wave of lonliness comes over me it generally is because I notice how little people really know me and how seemingly uninterested they are in doing so. However, part of this is that, for many of my acquaintances, fairly surface relationships are normal, so there is usually nothing more to know. I am simply not wired that way, but they sure are. I suppose, given how pervasive this dynamic is in my normal existance, that I should feel lonely more often, but I think I have adjusted my expectations over time to accept the way things are as being normal. Now that I think of it, I can actually handle lonliness...it is the opposite that would probably drive me buggy!!!!
