My bully can beat up my momma

Daughter 2 came racing down the sidewalk toward the minivan today after school.  There was a boy chasing her.  This is not anything different than any other day.  Daughter 2's a very competitive kid to say the least.  What was different was that the boy was smiling, even though he was losing, and Daughter 2, even though she was winning, was not smiling.
