Here you will find the Poem A Dream Pang of poet Robert Frost
I had withdrawn in forest, and my song Was swallowed up in leaves that blew alway; And to the forest edge you came one day (This was my dream) and looked and pondered long, But did not enter, though the wish was strong: You shook your pensive head as who should say, `I dare not?too far in his footsteps stray? He must seek me would he undo the wrong. Not far, but near, I stood and saw it all Behind low boughs the trees let down outside; And the sweet pang it cost me not to call And tell you that I saw does still abide. But ?tis not true that thus I dwelt aloof, For the wood wakes, and you are here for proof.
