Many young persons believe themselves natural when they are only impolite and coarse. François de La Rochefoucauld
The world is a looking-glass, and gives back to every man the reflection of his own face. Frown at it, and it will in turn look sourly upon you; laugh at it and with it, and it is a jolly kind companion; and so let all young persons take their choice. William Makepeace Thackeray
