In Cuba, there are institutions usually vulnerable to the deviation of their resources. One of them is the state carpentry. Taking advantage of my relationship with the watchman of certain carpentry, I obtained a determined amount of wood from this institution, to use it for building a watching post to be located inside the very same institution. Such building is the result of a paradoxically useful fact. The Watching post was placed in a zone suitable for controlling activities of a similar nature to the one I used to create it. This post could be used either by the same watchman involved in the wood extraction, or by other having the same function at this carpentry area.
