Not really, but some things have already been mentioned that can help reduce that kind of trouble. One of the first things I try to do is to know or to discover why someone is asking a question. So, sometimes I ask "Why do you ask?" before offering any kind of answer. Phone solicitors and/or debt collectors used to be troublesome for me, as another example, but now I just say "I do not answer questions on the phone" and stop talking. Sometimes someone will next ask why I do not answer questions on the phone, and I only just offer the same statement: "I do not answer even that question on the phone." It is not that I have become suspicious of everyone, but 1) there actually are some security issues there and 2) I have learned I can usually trust people who are willing for questions and answers to be an even exchange. Anyone who pressures me is likely trying to get something from me or at my expense, so I no longer "spurt things out" under pressure.
