What are some best practices for people who learn from afar of the passing of an individual (not immediate family) and who want show their respects to the deceased and the surviving family?
If they can choose to attend the funeral only but not the burial, or the burial but not the funeral, or pay a Shiv'ah call, which should take priority?
When is the appropriate time to call by phone?
Is email (or other electronic communication) an appropriate medium to express condolences?
Feel free to add other ideas, such as charity, flowers, etc.
