Thomas Hardy - At Mayfair Lodgings lyrics

How could I be aware, The opposite window eyeing As I lay listless there, That through its blinds was dying One I had rated rare Before I had set me sighing For another more fair? Had the house-front been gla**, My vision unobscuring, Could aught have come to pa** More happiness-insuring To her, loved as a la** When spouseless, all-alluring? I reckon not, alas! So, the square window stood, Steadily night-long shining In my close neighbourhood, Who looked forth undivining That soon would go for good One there in pain reclining, Unpardoned, unadieu'd. Silently screened from view Her tragedy was ending That need not have come due Had she been less unbending. How near, near were we two At that last vital rending, - And neither of us knew!
