Social networking?

You know, Facebook is kind of sad when you were never the popular kid. There are lots of people from my past that I remember fondly, and it's always exciting to find them on some website, to see what they've been up to and what they look like now. I'm happy to see them. I like to talk to them, hear how they've been, and all of that. And that's great.
I've come to realize, however, that such "relationships" leave me cold. This is unsurprising, and probably not unusual, but I think it goes deeper than that. Because I spend (too much) time on things like Facebook, I see the interactions that my friends have with their friends. They're all so excited to see each other! And they go into immediate reminiscences, and they often call each other to catch up, and maybe even meet up. And I guess what I realize is that I have always been on the periphery.
I was never the popular kid. In grade school, I was the antithesis of the popular kid. In high school and college, I thought that I fit in more, but I guess people still held me at arm's length. There are no "Hey, remember when"s and "I was just talking about you"s and "Call me, let's get together"s. There are certainly practical reasons for that, most notably the fact that I live nowhere near most of these people. And I admit that there are some people I never knew that well due to my own disinterest or some other reason. But ultimately ... I think of the quote from the film version of Sense & Sensibility when Willoughby says of Brandon that he is the sort of person that "everyone thinks highly of, but no-one remembers to talk to".
I think that I am just a person that people encountered on the way rather than someone they remember fondly or wish to reconnect with. I'm just that girl, the little one that everyone picked on, or the one who dressed funny and didn't wear shoes, or the one who showed up at lots of fencing tournaments. I suppose that I shouldn't complain, as there are most likely a whole slew of people that nobody remembers at all. But it makes me sad. What people don't realize about me is that all I have ever wanted in my life was to fit in somewhere. Be normal. One of them. But I was somehow always the unusual one, and the more people treated me as such, the more I suppose it came true.
There's worse, though, and that's the people that I realize want largely nothing to do with me, and some who I know don't even like me anymore. It makes me realize that I must've done something, or been someone that they didn't like or that made them unhappy. I suppose some have just moved on and don't care one way or the other.
At the bottom of it, though, is that same little girl who never uttered a word and never cried, but who only wanted to be included and loved. I still try so hard, maybe too hard, to make people happy or make them like me or just make them feel good because I like making people feel happy. I do it freely, yes; but doesn't every one want something in return? I remind myself to look for that love and acceptance from the few close friends I do have, from my husband, from myself ... but I don't think I ever got over not having it from the people I grew up with, and I wonder if I will ever stop looking for it now.
