The thorn in the brush,
The thorn in your side,
The thorn you contend with,
The thorn you despise,
The thorn that goes on, long after you are gone,
The thorn that sings your passionate song,
The thorn that makes a roses life go on...

Into......

The rose in the bushes,
The rose of your eye,
The rose you hunger for,
The rose you admire,
The rose that always keeps you close,
The rose that writes your marvelous story the most,
The rose that is reborn under the protection of the thorns...
