Peter and some of his friends have started a club, they meeting in a treehouse. Bobby wants to join, and although they think Bobby's too little to join, Peter convinces them to let him join as a junior member, who pays dues and does menial jobs for them. Climbing up into the treehouse for the first time, Bobby slips, falls and in the process sprains his ankle. But what may be more damaged than Bobby's ankle is his psyche, he who develops a fear of heights, which he doesn't even realize until after his several day bedridden recovery and his first time attempting to climb back up into the treehouse. Not wanting to show his fear, he feigns his ankle still being injured as the reason he can't climb yet. Without telling Bobby as such, the family does whatever they can to help him get over this fear. But dealing with other things that are more important to Bobby may be what it takes for him to overcome this fear. Written by
