Requited

This is how it goes-
One day
There was a man who fell in love
But she loved another
And so it went for years and years-
He never stopped pining
He never married-
Wished her a long and happy life at her wedding
Then drowned his sorrows when no one watched
Bid her good morning every day
And gave his condolences the day her husband passed-
Silently smiling
It was time
She welcomed him the first time-
He bought flowers for her the second
Asked him to stay for dinner the third
And by the fifth she realised-
She loved him-
Asked him to stay the sixth, the seventh-
And for every day after
This is how it goes...
