Only the most emotional and motivated, under the influence of pheromones, will proclaim his love by writing in stone, or on a tree. Politicians will advise you only to say it, so that you can "walk it back," if someone with any standing protests; a would be suitor from 6th grade.
Nevertheless, writing in stone, or wood, often provides immediate results, thereby avoiding the long courtship.
The picture and the artwork behind the words give the illusion of either being written in stone or carved into a tree. The writer met the challenge and created something quite romantically beautiful also. I give credit and kudos to this artist who made this work so well and my thanks
