5. Give a talk, then lead a discussion

Warning. TWO JOBS, AND ONLY THE FIRST ONE GETS REHEARSED. Giving a talk is preparation you control entirely. Leading a discussion is not: it means having a question ready that somebody can actually answer, being willing to sit through the silence after you ask it, and doing something sensible with whatever comes back. Prepare three or four questions rather than one, and expect to need the second. Note also that the two halves have different subjects. The talk is about how people from different groups HAVE GOT ALONG; the discussion is about what CAN BE DONE to help groups understand one another better. Past and future, and it is easy to give one talk covering both and then have nothing left to discuss.
