Don't flatter yourself that friendship authorizes you to say disagreeable things to your intimates. The nearer you come into relation with a person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare, leave your friend to learn unpleasant things from his enemies; they are ready enough to tell them.

Nobody’s enemy but his own.

If you want to make enemies, try to change something.

Sir, no man’s enemy, forgiving all
But will his negative inversion, be prodigal.

Want to keep Christ in Christmas? Feed the hungry, clothe the naked, forgive the guilty, welcome the unwanted, care for the ill, love your enemies, and do unto others as you would have done unto you.
