I am very sorry for your loss, especially so close to Christmas . I tend to grieve in the presence of only my closest friend and husband. I am a quiet griever. I think you are right, we are all different in how we deal with grief. My own mother acts as though she wants me to put on a performance while grieving and break down in public. I am just not like that. However, the last thing I am thinking about while grieving is etiquette.
