I answered the phone and the caller addressed me, using my wife's last name. Our number is listed under her first initial and last name. Since she kept her name and didn't take mine, it's always a tip off for me when a caller calls me by her last name. I asked who was calling. He said "public safety," and asked for Mr. or Mrs. my-wife's-last-name, and started saying sometthing about confirming some information. I again asked who was calling, and noted that "public safety" is a pretty generic term. The caller then said, "Obviously  Mr. or Mrs. my-wife's-last-name isn't there, so you have a nice evening," and he hung up. Not sure if this was a thwarted scam or what, but I had the distinct sense he wanted to get information without giving any.
