If your child came home and said, "My friend said that my teacher is quitting in February because she said she hates all of her students," would you:
A) Tell your child that that obviously sounds like a rumor, and you're certain it's not true. Perhaps suggest that instead of listening to rumors, she just ask her teacher.
B) Keep your child home from school, then call the principal and ask if he knows that one of his teachers is quitting because she hates her students, and tell him that your child was too distraught to come to school today.
(For those wondering, I would choose A. The parent of which I am HYPOTHETICALLY speaking, chose B.)
