No bad news

After hanging up this sign on Sunday cautioning the neighbors to be careful, the lobby staff called me to complain that they were mazuii (yukky) and I was giving people bad feelings. They took the sign down; apparently it’s not acceptable to let the neighbors know about the robberies.
That makes no sense to me; if my neighbor had been burgled I would want to know so I could take extra care to lock my doors and watch for strangers. I wonder what else has happened in the building that the management has swept under the rug.
