Veltz Meshugener,
The problem with learning shmiras halashon is that it turns out everything is forbidden.
From my vantage point, the L”H problem here is not that the OP mentioned that a neighbor broke one of his chairs and asked whether he should ask the neighbor to pay for the damages since he wants to remain on good terms. That type of situation happens all of the time and the question phrased that way carries no risk of embarrassing or identifying anyone.
The problem with this OP, however, is all of the personal details supplied, such as the approximate time the person moved in, the number of children he has, his social habits, and additionally some unusual and unique features of the incident that have no bearing on the question but would render it recognizable to anyone reading this thread who was there or knows this person. None of these details were needed to ask the question, so given the fact that they carry the risk of embarrassing this neighbor, they should not have been supplied. Five details that, standing alone, couldn’t identify someone specifically may very well identify that person when taken together.
If I had a vote, it would be to edit the OP to remove the details, but keep the question.
