The Lost Boys, from the Peter Pan stories, are portrayed in some films to have odd names like 'don't ask' and 'too small'. In Hook, especially, one Lost Boy named 'thud butt' explains his happy thought is his mother. They all seem to portray their happy thoughts as actual memories that seem faded. Isn't it interesting to realise that its that 'happy thought' that can give you the ability to fly away, is really like a fractured memory, and thus they are lost, between worlds, between never growing up and never really remembering.
