Last night Middle Boy brought me home some change from a purchase he had made after school.

This morning it is missing.  I asked where it was and "no one" knew.

Finally Middle Boy told me he thought he could "find it". 

You'll never guess where it was...in his room with "his money".

He told me he must have gotten confused and put it in with his money.  "Besides...it isn't like I need the money."
