One for sorrow. Two for joy!
One for sorrow, two for joy, three for a girl, four for a boy, five for silver six for gold, seven for a secret never to be told. The old rhyme originally applied to magpies. One hardly sees magpies in Mumbai. Over time people used the rhyme for crows. Crows are wonderfully interesting creatures and we should all pay more attention to them. I am particularly fond of seeing them in twos. They tend to show up in twos when I need guidance of some sort from the world around me. So yes, two crows are always for joy!
