Nothing is more dangerous than a friend without discretion; even a prudent enemy is preferable.

Jean de La Fontaine

Always be careful of your friend who loves your enemy; you either trust such a fellow for your life or for your death.

Ernest Agyemang Yeboah

If people ever question your loyalty, you never had theirs.

Justin McFarlane

Be wary of authorities who befriend a person for their own purposes. They appear loving when it is beneficial to them, but do not stand by the other person in his time of distress.

Rabban Gamliel, Avot 2:3

America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.

Abraham Lincoln

Be loyal to those who are not present. In doing so, you build the trust of those who are present.

Stephen Covey
