Stimulants to horrid thoughts
A shirt caught up in a tree
Road litter of biomorphic aspect
A child’s falling behind the striding parent

Stimulants to beatific thoughts
The sunset after the sunset
An object made for its own sake
The cool of the forest shadow

Stimulants to ambivalent thoughts
A child’s exploration of pain and its causes
A pair of hawks riding the thermals
A child’s concentration at tap dance class
