Turning the Homework Tables

Every night we review the girls' homework.  We let them know what needs to be corrected, without correcting it ourselves. 
One day they came home and the blond twin was mad at me.  She said, "You checked my homework and I still got one wrong."  I apologized and said, "I must not have understood the directions."
From that moment, only Daddy could check her math homework. 
Recently, the girls decided to create homework for their parents.  The blond twin wrote pages and pages of math homework for her Daddy.  She was determined to make sure he knew how to do the work she was learning.
The brunette twin took a different direction.  She wrote math homework for me, but she also included some handwriting exercises.  It seems she thinks my  handwriting could use some work.
When I told my husband he said, "Well, she knows two of your weaknesses."
The sad part is I couldn't really argue. He was right.
