Let's not come down too hard on FIL. First of all, can we assume that he is well informed about the real relationship between W and OM? No. She's told him some story where the two of them are just innocent employees discussing important company policy and everyone is making up stories about them. And then OMW gets a crazy bug and decides to call OIN just to make trouble. So of course he says, "forget them." And, actually, it is good advice. Forget them. We wish she would!
