Today Brother was picking up toys in the basement. He called me in to tell me, "Well, you see I started in my room and just got carried away. I think I did the whole house." And he did. He picked up this and that and everything and made a solid effort to find its home. He even made his bed. That was hilarious.
Best part was he kept saying he was done then finding yet another toy, "Oh no, not another one," he kept saying. But then he'd just pick that up because as he said, he just got carried away.
Yes, we train them well, in that moment at least.
