One of my best memories in the whole world was being awake in the middle of the night in my big old drafty house and feeling lonely and alone (this was 10+ years ago) and coming online to a community and there was one person, who lived in western Canada I think and we sort of greeted each other and exchanged pleasantries about what I was eating :-) and it was so comforting to me and I went back to bed knowing there were people awake somewhere in the world, "watching out". I went right back to sleep, like a little kid.
