In light of the ethics rules we must respect in our work as members, it is as though we, from one day to the next, suddenly had no lives. I am exaggerating, but I'll put the expression in quotes. We can no longer speak to the people we know in the same way. During a friendly encounter, if the conversation turns to a work topic, we are dismayed, because we have to tell the person we are speaking to that he has to send us a bill if he wants us to continue the conversation, because the topic has gone beyond the friendly boundaries that defined the encounter in the beginning.
For you, the challenge is to look at things on a case-by-case basis and to do a subjective assessment of the facts that are submitted to you. For their part, the MPs feel they can no longer speak to anyone, for fear that a conversation, innocuous in the beginning, could evolve and put them in a compromising position, and that that meeting be misinterpreted.
