I told my kids that I had to drop them off at my wife's apartment promptly at 7:00 pm because she was going to take them to a restaurant. The 7-year-old said, "we're probably just going to Bruce's house. We are supposed to call it the restaurant instead of Bruce's house."
Bruce is my wife's secret boyfriend. I wasn't supposed to know about him, but I had to admit in deposition that I knew about him, and that she and the kids sleep over with him on a regular basis. Apparently my wife had thought that she had sufficiently brainwashed the kids to conceal what was going on.
