I have come to the conclusion Bill never sleeps!
Megan, thanks for your sympathy on the loss of my brother. It is very hard for my mother still, especially on Christmas. She is getting to be old and has brain damage from an undiagnosed heart condition that makes her delightfully forgetful. My father and I have an unwritten pact not to discuss the day or date if it will make my mom remember it had significance to her and my brother. I know it sounds cruel but it makes life much smoother.
You are going to face friends who want to express sympathy and ask questions and not know what to do. They like you and want to support you, just remember that. If they want to talk and you are okay with that, do it. If they don't want to discuss your brother at all ever, try to be okay with that. When I lost a dear friend last summer I couldn't even approach her husband at the memorial, which I later explained to him and he said was okay. I'm thinking about you, been brooding all day, wanting to help, wanting to talk to your mom and dad and the rest if the kids and tell them that all is horrible now the depth of the sorrow will shift.
Karen
