If you decide to have a long lunch with your husband... on a Friday... when you typically only get 30 minutes for lunch... don't tell your boss that you have a dentist appointment.
Which I did.
And lo and behold, when I got back to the office, Rick had a question for me and called my office. On my phone.
And my boss answered my phone.
And my husband began to flirt with her. Along with telling her 'thanks for lunch.' And once he figured out who she was, he apologized and told her that he had just seen me for lunch and needed to ask me a question.
