"The Tide Rises, The Tide Falls" is a poem written by <em><u>Henry Wadsworth Longfellow.</u></em> Since it is a poem, it means that the words in it must not be taken literally for they have deeper meanings. The "tide" in his poem symbolizes the forces in life. <em>When the tide rises, it means that good things happen and when the tide falls, it means bad things happen. </em>This also means that every person experiences such tides in his life until he dies. The cycle continues to other people, those who are born also experiences such opposite forces in life.
