Bottles numbered three

The papier-mâché bottles
Three I get each night
Formed entirely beautifully
And all of them invite
Us users to drink water
And use them carefully
Standing to attention
As happy as can be

They sit fair and squarely
Gasping for our fuel
And they take the ward light shadow well
It seems that it’s the rule
Of thumb to do it carefully
An opportunity
To relax into the ablution
Just let it all run free.
