Back From a Two-years' Sentence

Back from a two-years' sentence!     And though it had been ten,     You think, I were scarred no deeper     In the eyes of my fellow-men.     "My fellow-men?" Sounds like a satire,     You think - and I so allow,     Here in my home since childhood,     Yet more than a stranger now!     Pardon! Not wholly a stranger,     For I have a wife and child:     That woman has wept for two long years,     And yet last night she smiled!     Smiled, as I leapt from the platform     Of the midnight train, and then -     All that I knew was that smile of hers,     And our babe in my arms again!     Back from a two-years' sentence -     But I've thought the whole thing through,     A hint of it came when the bars swung back     And I looked straight up in the blue     Of the blessed skies with my hat off!     O-ho! I've a wife and child:     That woman has wept for two long years,     And yet last night she smiled!
