When should I talk?

As you feel it is right.  Many discussions can take place over a period of time, and are not just one conversation.  For example, you may need to ask people if they will act on your behalf, and give them time to think about their response, and discuss more details later.  Alternatively, you may just want to convey information or arrangements that you have made, for example that you have signed up for organ donation.
