Rielee the frustrated teacher

 Rielee found it was very hard on her knees to play piggy-back with the twins.

 But they sure had a good time.

When they were playing school, Rielee first read Brown Bear, Brown Bear to the girls.  At the end, it is about a teacher looking at her children.  She finished the book, closed it,  and said to the girls in her serious teacher voice, "for the most part a teacher is a mammal.  You see, we are animals."  Ava and Harper just stared at her blankly, then looked at each other, not understanding her interpretation of the book.  Rielee sighed and went on to the next book.
