I was looking for a poem for you today and I think I have found one of the shortest peoms I have on my Kindle. This was written by Heny David Thoreau (1817 - 1862) and I located it in Great Short Poems, Edited by Paul Negri, Dover Thrift edition.
It is a thoughtful little peom. Two lines, with a sense of truth. Simple yet thoughtful. Some of us spend too much time uttering rather than living. Some of us live to fullest but have nothing to utter when the day is finished. See, it is a thoughtful little poem if you think over it a little.
