A good friend of mine from work just lost her father suddently. The family will be sitting Shiva all week. I'm not Jewish, so I'm at a loss for what is expected. I definately want to go. Is there a proper "protocol" so to speak about what to wear, what to bring, when/when not to go (time of day), how long to say, etc? She is orthodox, but her mother is not. Help! I just want to do the right thing.
