Nobody knows that you have died yet. You now can say goodbye to only one person and have 24 hours to get to that person, and can only spend 2 hours with them. Who would you say your final goodbye to? Would you say goodbye to anyone at all?
Personally I know who I would say goodbye to, a person who is very close to me. I'd feel very selfish for not saying goodbye to one of my family like my mom or my dad but I'd still say goodbye to the same person.
