“So, we have kids who do the same activity and I emailed the coach one weekend, kind of being funny about my kid and saying, ‘Well, this one seems to be getting a little womped this weekend,’ " she recalled. “‘So, what does that mean for tomorrow morning because we have something planned? What does that mean typically?’ And I was being funny, I thought I was being funny.”

“Turns out it was the one time in my life I replied all,” Garner added. “I replied to everyone on the team, to every parent, including you and Helen.”
