I always just asked to set by people that were alone

I always just asked to set by people that were alone. I don't always feel lonely but I always wanted to keep other people from having to feeling lonely or an outsider. And I have always understood that you can feel that way around people too. I don't really remember why or when I started doing it, I know I was doing it at 8. I didn't make people talk with me but I would talk if they did. I never really cared if I had friends but didn't like seeing other sad or lonely. I didn't think me sitting by them would make them happy but maybe they'd feel safer or something.
