what's wrong in the world
Not so much that the mom called the cops... in this day and age, you can't be too careful about what may get you accused of child abuse.
Not so much that the kids were fighting over something, and it got a little physical. Six year olds can get a little... spirited sometimes.
It's that they were fighting over a pacifier. A BINKY. Six year olds are TOO OLD FOR BINKIES!! That's what's wrong with the world--letting your six year old have a pacifier.
