"Îmi place să privesc afară.
-Când au căzut aceste frunze?
Și arborii se scuturară,
Și-n vizuini adânci,ascunse,

Stau vulpi roșcate. Stoluri, salbe,
Peste pădure nori de ceață,
Ca niște zburătoare albe
Plutind de vârfuri se agață [...]

Și liniștea cu aripi ușoare,
Prin mii de pori respiră-n toamnă
Doar plopii mistuiți în zare
Spre depărt
