Quote by Oliver Wendell Holmes
Stillness and steadiness of features are signal marks of good breeding. Vulgar persons can't sit still, or at least must always work their limbs and features.
Summary
This quote suggests that calmness and composure in one's facial expression and body language are indicators of good manners and upbringing. It implies that those who lack refinement or come from a lower social class tend to display restlessness or a constant need to move their body parts. By contrasting the ability to sit still with the tendency to fidget, the quote implies that individuals with good breeding possess a certain grace and self-control that sets them apart from those considered vulgar or uncultured.
