takenoko to shinayoku asobe suzume no ko
bamboo shoots, baby sparrows
by Issa, 1819
Issa's word, shinayoku, seems to be a variant of shinayaka: graceful, elegant, delicate. In his haiku, he tells the baby bamboo and baby sparrows to play together delicately, gracefully.
Why did Issa order baby sparrows to play gently?
Because a bamboo baby was his beloved daughter.
