A child's real grievance, done seriously: why must bed come while the sky is still blue and the birds are still hopping about outside? Stevenson never talks down to the complaint, which is exactly why it works read aloud to a small person who has made the same argument themselves.
From A Child's Garden of Verses. See the whole collection.
In winter I get up at night
And dress by yellow candle-light.
In summer, quite the other way,
I have to go to bed by day.
I have to go to bed and see
The birds still hopping on the tree,
Or hear the grown-up people's feet
Still going past me in the street.
And does it not seem hard to you,
When all the sky is clear and blue,
And I should like so much to play,
To have to go to bed by day?
