For some groups concerned with some subjects, the opening presents few problems. Just as many conversations begin without an artificially contrived opening, so in an adult class a brief sentence may be all that is required. Usually this happens when the topic is well known to the group, when perhaps the discussion is being used to deepen understanding of already familiar material, and certainly
it needs good relationships and a relaxed atmosphere. Other subjects, however, may require a short introduction, both to provide some basic new information and to focus the mind of the group on the subject. It may also be necessary to provide an introduction which gives time for people to settle down and relax, especially if members have travelled long distances or have come straight from work. What has to be remembered is that the longer the introduction the less easy it is for the conversation to start; people sit back to listen and it requires more and more effort for them to change into active participants. A leader is therefore well advised to keep his introduction as brief as possible, provided that it achieves three objectives: to show the purpose, to focus attention on the topic and to give time for the group to settle down.
