"Now I was young and easy under the apple boughs about the lilting house and happy as the grass was green." are lines in the 1945 poem, 'Fern Hill' by Dylan Thomas. Literary critics reported that Thomas's 'Fern Hill' began as an evocation of his childhood visits to his aunt's farm, which expands into dreamlike metaphors and a lament for lost youth. There are six stanzas of praise and then lamenting ideas.

In 'Fern Hill', the speaker is stoked about running through the countryside. Within the poem, he talks about how happy he was as a youngster and how oblivious it is for him to see that his youth is passing. The whole poem is one that vividly depicts time´s influence on a person's entire existence.

At the end of the poem, the tone shifts dramatically from joy to lamentation. It's almost as if a person is singing the song, "If you're happy and you know it, think again!" What was a carefree bliss for the speaker turns out to be a fleeting joy that he never can recapture. This is all about "seize the day." Dylan Thomas was a master of form and meter, and he never shines more than he does in "Fern Hill." This poem is seen as one that "crosses temporal boundaries to guarantee its essential purpose."
