True friends are the whole world to one another; and he that is a friend to himself is also a friend to mankind. Even in my studies the greatest delight I take is of imparting it to others; for there is no relish to me in the possessing of anything without a partner.
Seneca the YoungerThere are more people abusive to others than lie open to abuse themselves; but the humor goes round, and he that laughs at me today will have somebody to laugh at him tomorrow.
Seneca the Younger
