காக்கை கரைந்தால் விருந்து வரும்
Kaakkai karaindhaal virundhu varum
Meaning
A crow's caw was traditionally read as a sign that a guest was on the way - old folk wisdom around noticing small, everyday omens.
Story
A crow cawed persistently in the courtyard early one morning. Smiling, the grandmother said, "someone is coming today - get the cooking started." By afternoon, a relative no one had seen in years arrived unannounced.
Reader's Note
Whether or not you take the belief literally, noticing small everyday signs is really a habit of paying closer attention to the world around you.
