William Wordsworth seems to have had a soft spot in his heart for both Nature and Youth. Both, he perceives have innocence. One poem by Wordsworth which illustrates this point very well is from the Lyrical Ballads 'Anecdote for Fathers.'
In this simple warm and heartfelt poem, he outlines a walk between a father and a young child in which they discuss the merits and demerits of the country homes they have lived in and which the young son prefers.
The child is refreshing in his innocent honesty, and says he prefers the old house! However, despite his tender five or so years, there is the dawning of a more mature realisation of how one human's words affect another's feelings. On seeing the father's surprise (and perhaps disappointment) the child appears to cover what he said, perhaps to sweeten the pill. He adds he only liked Kilve (the old house) better because of it's weather vane. Wordsworth may have been touched by a story of a child's tender feelings towards a father he didn't want to hurt.
The poet had many siblings himself and was separated from them a lot when their parents died during their childhood. He was also very close to his sister Dorothy with whom he shared an awe of nature.
