meara, the morning my father died I went into the SF office as usual and one of my favourite colleagues asked me, "Are you all right? You seem a little thinkier than usual," and I just sort of looked at her and said, "My father passed away this morning." Her response was, "What are you even doing here?" and I had to say, "Most of the people who care about me are here. If I fall over, they'll catch me."
Obviously, your work situation may be different. But everyone does this a little differently, and what is right for you is right for you. We love you, and we will support you no matter what you need to do.
