9 years old

We are so proud and admired of how Pinky has grown! He shows more responsibility, independence, obedience, and ability to get along with others. Feelings of empathy and altruism are apparent in him, and he is a good and devoted friend. Just now he was making a little gift for his friend Jake and felt really thrilled about how happy he was going to make him feel. Pinky is no quite self-sufficient, he does his homeworks without been told, tries to maintain things in order and even helps prepare his meals.He's mature now, he recognizes when he has done wrong, but also when he has failed to do right. He will confess to us when he has done wrong, because his conscience bothers him until he does. He is somewhat less likely to try to blame or excuse his actions, but still uses these tactics when he is embarrassed or ashamed.
