Marks in school

When my kids were in school, they thought it was for social interaction not learning.  When report card time came it was unbelievable.  Bobby always thought he did good because he had one of everything. He was the class clown.  Grace thought the lower the mark the better.  Stacy would goof off till progress reports came then pull her marks up.  The two older ones have actually hid their report cards until a neighbor asked how they did.  They would even try to get the mail before me to intercept them.  Caught again.  Now I sit back and listen to Bobby checking up on the girls marks.  He insists that they bring home C's and above, which they all do.  Shoe is on the other foot now.  Paybacks are fun!....
