@gromit, I actually got that off Discworld: Noir. I remembered it a couple days ago and thought it would be a better signature. Since my old one was getting, well, old. Although it is one I agree with, in the majority of cases, people wouldn't be friends with each other if there was nothing to gain. In every friendship I have seen in other people, there was always something they got from each other that made the friendship worthwhile. Or certain criteria that had to be met in order for the friendship to continue, e.g. a way of thinking or a belief. So even if someone wasn't getting any material objects, they were gaining an ideological ally, someone expected to support them.

@Indy11, I apologise for my outburst. I've been having a rough few months lately. And I was not aware that giving a warning as to the subject of a post was inviting people to read it. Obviously I don't use forums as much as I should in order to obtain that kind of knowledge. I had seen someone do it in one of their posts, and I decided it would be useful to apply that technique to my post.

Friends are just people who have used each other so often it has become habitual.
