FUNERALS FOR NOT FAMILY

I don't really know how to do them
  1. What do you put on the card when you send flowers?
  2. How do you sign things?
  3. What do you say to people?
  4. I keep trying to think of the most meaningful stuff people have said or helpful things they've done and all I can think of are "beer and toilet paper"
