You can't expect everyone to be good at things.
James, and avid and experienced rock climber, is planning a trip for himself and some friends to a canyon.
James wants to decide whether to include a rock climbing session in the trip.
James decides to omit the activity as he remembers at least a couple of his friends are older and probably wouldn't like rock climbing.
James decides that since he loves rock climbing he will go ahead and include the activity in the trip planning.
James friends have a great trip together and no one is embarrassed about their inadequacies.
Once James' friends find out about the rock climbing they're disappointed as they're physically unable to take part and thus feel left out.
