I have a problem that isn't mine but may become my problem. I am working for a woman with two amazing children and a new live in boyfriend. He is always polite to me and acts completely normal most of the time. The problem is, when my boss leaves the house and he is home, he is going all through her house. He only moved in in January. Gradually he has become more and more comfortable going through things. I have even seen him retrieve mail from the mailbox and steam it open. I ignore him and pretend I don't see what I'm seeing. My female boss is so nice. I don't want to give her any bad news, but all his sifting through her things makes me think she is going to eventually think I am the one going through her things. Do I say anything? If so, how?
