    ... all my letters are read. I like that. I usually put something in there that I would like the staff to see. If some of the staff are lazy and choose not to read the mail, I usually write on the envelope “Legal Mail.” This way it will surely be read. It’s important that we educate everybody as we go along.
    Jean Gump, U.S. pacifist. As quoted in The Great Divide, book 2, section 10, by Studs Terkel (1988)

    I believe in the brotherhood of man, all men, but I don’t believe in brotherhood with anybody who doesn’t want brotherhood with me. I believe in treating people right, but I’m not going to waste my time trying to treat somebody right who doesn’t know how to return the treatment.
    Malcolm X (1925–1965)

    It may have been observed that there is no regular path for getting out of love as there is for getting in. Some people look upon marriage as a short cut that way, but it has been known to fail.
