My son got in big trouble at school.  He was very mean to his best friend, and I had to call his mom and explain what had happened.
That's terrible when friends fight. What was it over?
He wasn't even upset with his friend, he was upset with someone else.  I felt so bad having to explain it to his friends mom.
That's got to be a tough phone call to make. Did you two make amends or is she very upset?
She was fine with it.  She knew he was in big trouble at home.
Uh oh don't want to be that kid that's for sure!
