Why

I have been on EP for several years, on SW for less, purely to make contact with the outside world. I often come on here feeling positive, but every so often someone makes me wonder about their sanity, their reason for being on here. Then I wonder about my own reasons, never reaching a firm conclusion, does there have to be a reason. Every one is different, but some seem to be here just to bully others, why the need when all of us (unless we meet) are just words on a page.
