Pencil of Doom

There's two friends, they are always with me, a child and a dog, the child wants to play, happy when i play, always smiling at me, loves me, calls me Papa, cares about me, the dog, called "Ego", follows me wherever i go, respects me, acknowledges me as it's master, never barks, and interesting.
The child is innocent, fragile, positive, sees me as a father, the dog is loyal, respectful, quiet, reserved, a fascinating creature.
