occasions that celebrate special events or that mark the beginning of end of a process often call for an after-dinner speech. political rallies, award banquets, the kickoff ofa fund-rasing campaign, or the end of the school year may provide the setting for such a speech. in keeping with the nature of the occasion, after-dinner speeches should not be too difficult to digest. speakers making these presentations usually do not introduce radical ideas that require listeners to rethink their values or that ask for dramatic changes in belief or behavior. (1)none are such occasions the time for anger or negativity. (2) they are a time for people to savor who they are, what they have done, or what they wish to do.
