Important things often require great care. Take discussions with the family about estate planning issues for instance. Talking with one's family about one's estate plan can be a very important thing. It can help create clear expectations within a person's family regarding what will happen asset-wise when the person passes away. It can also help bring potential issues and concerns regarding such matters within a family to the front early, thus giving a family a chance to properly address them. These sorts of things may be able to help things go easier for a person's family during the probate process after the person has passed away.
It is, however, possible for such discussions to go awry. Discussions on estate planning can touch on some sensitive issues for a family, and thus could rather easily go into troublesome territory when not handled with careful thought. An estate planning discussion with one's family going badly could have many negative implications, including hurt feelings and increased difficulty in having constructive conversations about these topics in the future.
