Each individual comes to the trip not only with an expectation to complete the journey as they understand it, but also with personal needs and expectations. Many of these will remain unexpressed. They might include such considerations as having an enjoyable social time, making new friends, getting a good fitness workout or spotting particular birds. A good leader/facilitator will pick up some of these needs and at least acknowledge them even if they can’t be met. The needs of the group as a whole will be a combination of all of these needs but will also be skewed by the personalities involved and their impact on the overall group dynamics. The skilled leader will often have a sixth sense about how these processes balance out.
