Good Boy!

I will say that to compliment Tony, or to indicate to him that he has done something right.

 

Now, he will say that to me.

 

Case in point:  just tonight, Tony was begging me to do something with his train set.  I had set the tracks up in their normal configuration,  but Tony kept pulling pieces of track away.  He would then say some unintelligible and point at the track.  For the longest time, I couldn't figure what it was he wanted.  So, I decided to set up the tracks in a different shape or, you could say, configuration.  What had once been a rectangular kind of shaped configuration (with curved ends) became perfectly circular -- Tony was pleased by this, and said "good boy!" to me.
