Stop Talking Now

My best friend made the mistake of saying something complimentary to her passive-aggressive coworker. The coworker immediately questioned the compliment.

Later the same morning, my friend told the p/a coworker that her son had been scheduled for a class taught by his father.

Coworker's response: "Is that legal?" (Notice: not "Is that a good idea?" or "How does he feel about that?" but a suggestion of a possible crime in progress)

Must remind best friend not to say anything to p/a coworker unless absolutely necessary.
