Some kids tell their parents everything that goes on in school.
At least, that’s what I’ve heard. My kids certainly never did. My older daughter, in particular, considered school to be her domain.
She established my outsider status her first day of nursery school, when I went to pick her up. Excited to hear about everything she had done, I asked her how her day went. Her response: “None of your business,” or something to that effect.
