Mad: Trees

One thing that could be said about the Petrellis was that they were all stubborn. Even as young as he was, Peter could hold onto an idea and refuse to let go no matter how many times his father denied him. This was something the boy desperately wanted but unlike with his puppy, Peter couldn’t depend on Santa to give it to him. This was something his father had to give.

( Most kids had tree houses, but that wasn't why Peter wanted one )
