The character of the chubby kid, "Piggy" still comes to mind when I think of any situation when there's a loner in a group. Piggy has asthma, glasses, he's overweight... but, by far the most entertaining character in this film.
I love his story of the town where he grew up "The true story of Camberley". He tells it to the little ones of the group of boys on the island, when everyone else is off hunting and gathering, figting and acting like animals.
I love Piggy, and may he rest in peace.
