It's sad that in a world of billions, people can still feel isolated and alone. Sometimes all it takes to brighten up someone's day is a smile or kind word, or the generous actions of a complete stranger. Small things, the tiny details, these are the things that matter in life — the little glint in the eye, curve of a lip, nod of a head, wave of a hand — such minuscule movements have huge ripple effects.
