You speak the truth. It's apparent David is a highly intelligent and imaginative kid who probably knows more than the adults surrounding him. Roger is better than he used to be, but still, all of the Collinses seem reserved, and there's virtually no affection given this kid at all. Bored, lonely, ignored--no wonder David fiddled with his father's bleeder valve and locked Vicki up in a deserted part of the house. He's crying for attention and no one is listening, and that can only elicit bad behavior as a means to getting that attention!
Love, Robin
