Wow, this one was terrific! The dramatic voice of Marge really conveyed her stress!  All of the seemingly inconsequential details fell right into place at the conclusion.  One could see how Billy might have inherited his willful, tempestuous streak, hey?  The only detail that 
 was a bit distracting was the use of an adult to portray a young boy. I think a real kid would have been a better choice.
