Splendour in the grass

I watched a movie for Natily Wood and Robert Wagner named "Splender in the grass". I really liked the movie and also I really admired the part of William Wordsworth's poem from which the movie name was taken. So here I am just putting that part of the poem.

From Wordsworth's "Ode: Intimations of Immortality from Recollections of Early Childhood" (starting at line 182):

Though nothing can bring back the hour

Of splendour in the grass, of glory in the flower;

We will grieve not, rather find

Strength in what remains behind
