Apologizing. — A very desperate habit, — one that is rarely cured. Apology is only egotism wrong side out. Nine times out of ten, the first thing a man’s companion knows of his shortcoming is from his apology. It is mighty presumptuous on your part to suppose your small failures of so much consequence that you must make a talk about them.

Oliver Wendell Holmes, Sr. (1809-1894) American poet, essayist, scholar
