Titon Rahmawan quote: “People who know etiquette will not speak in an arrogant and boastful manner. They will not intentionally attack or deme…”

“He was always boasting of his ancestors, as stupid people do who are aware that they have done nothing themselves to boast about.”

Robert Graves book I, Claudius

Context: My tutor I have already mentioned, Marcus Porcius Cato who was, in his own estimation at least, a living embodiment of that ancient Roman virtue which his ancestors had one after the other shown. He was always boasting of his ancestors, as stupid people do who are aware that they have done nothing themselves to boast about. He boasted particularly of Cato the Censor, who of all characters in Roman history is to me perhaps the most hateful, as having persistently championed the cause of "ancient virtue" and made it identical in the popular mind with churlishness, pedantry and harshness.

“Is it just me or does anyone else think, that the courage to speak up and express opinions should be accompanied by manners and etiquette?”

“Truly good manners are invisible: they ease the way for others, without drawing attention to themselves. It is no accident that the word "punctilious" ("attentive to formality or etiquette") comes from the same original root as punctuation.”

Lynne Truss (1955) British writer

“Dear Miss Manners: What about Easter? I suppose you have etiquette rules that apply to Easter Day?
Gentle Reader: Certainly, and when the Day of Judgment comes, Miss Manners will have etiquette rules to apply to that, as well.”

“This is not the first time that our people have had to deal with an attack of an arrogant foe.”

Vyacheslav Molotov (1890–1986) Soviet politician and diplomat

Context: This is not the first time that our people have had to deal with an attack of an arrogant foe. At the time of Napoleon’s invasion of Russia our people’s reply was war for the fatherland, and Napoleon suffered defeat and met his doom.
It will be the same with Hitler, who in his arrogance has proclaimed a new crusade against our country. The Red Army and our whole people will again wage victorious war for the fatherland, for our country, for honor, for liberty.
The government of the Soviet Union expresses the firm conviction that the whole population of our country, all workers, peasants and intellectuals, men and women, will conscientiously perform their duties and do their work. Our entire people must now stand solid and united as never before.
Each one of us must demand of himself and of others discipline, organization and self-denial worthy of real Soviet patriots, in order to provide for all the needs of the Red Army, Navy and Air Force, to insure victory over the enemy.
The government calls upon you, citizens of the Soviet Union, to rally still more closely around our glorious Bolshevist party, around our Soviet Government, around our great leader and comrade, Stalin. Ours is a righteous cause. The enemy shall be defeated. Victory will be ours.
