One element of lyric poetry is personal reflection. which lines in this poem most clearly illustrate that element? i wandered lonely as a cloudby william wordsworthi wandered lonely as a cloudthat floats on high o'er vales and hills,when all at once i saw a crowd,a host, of golden daffodils; beside the lake, beneath the trees,fluttering and dancing in the breeze.continuous as the stars that shineand twinkle on the milky way.they stretched in never-ending linealong the margin of a bay: ten thousand saw i at a glance,tossing their heads in sprightly dance.the waves beside them danced; but theyout-did the sparkling waves in glee: a poet could not but be gay.in such a jocund company: i gazed and gazed—but little thoughtwhat wealth the show to me had brought: for oft, when on my couch i liein vacant or in pensive mood,they flash upon that inward eyewhich is the bliss of solitude; and then my heart with pleasure fills,and dances with the daffodils.
