The Sparrow and the Crow
Retold for young children from Tales of the Punjab: Folklore of India (collected by Flora Annie Steel, 1894), public domain.
A sparrow and a crow decided to cook a pot of khichrī (rice and lentils) together for dinner, each bringing something to add to the pot. When it was ready, the sparrow — a rather bossy little cook — told the crow he was much too dirty to sit down and eat until he'd gone and washed properly.
So off the crow went to the pond to ask for water to wash in. But the pond said he'd need to dig a channel first, so he'd need a horn from the deer to dig with. The deer said he needed milk first to grow strong enough to spare his horn. The cow said she needed grass first before she could give milk. And so it went, from the grass to a blacksmith for a sickle to cut it, each new friend asking for one small favor before granting the next.
Patiently, politely, and without ever losing his temper, the crow visited each one in turn, asking nicely and working his way all the way down the line and then all the way back up again, gathering exactly what each helper needed.
By the time he made his way back to the pond with everything it needed, the water was finally his to use, and the crow washed himself clean from beak to tail feathers, then flew home at last to enjoy his fair share of the khichrī, patience rewarded.
Talk about it (ours, not from the source): the crow stayed patient through a whole long chain of favors just to get clean for dinner. What helps you stay patient when something takes a long time?
