Lie or Admit?

"Mommy, me and 14 other friends were punished at school this morning."
"Why? What did you all do wrong?"
"Teacher asked us not to play outside the class."
"And you didn't listen?"
"Yes, we played outside the class, got in sweat, and being punished by not allowing us to sit. We stood, facing the window."
"Hmmm..."
"Mommy, when Teacher asked who played outside, I raised my finger. Well, not very high but Teacher can still see it. I admit that I didn't listen to what Teacher said."
"And?"
"A friend of mine, he did go outside but he didn't admit and didn't get punished. Why he lied?"
"So you and other friends played outside and admitted when Teacher asked but one of your friends who played too, didn't admit and didn't being punished, is it right?"
"Yes."
"And how you feel about it?"
"Why he lied? He went to the church every Sunday and often yelled at me of not going to church. But now he lied and I didn't lie."
"Ok, you didn't listen to what your teacher had told you, that's wrong, for sure, understand?"
"Yeah..."
"But when being asked, you admitted your fault, that's right, got it?"
"Yup."
"Being punished is the consequence of not listening and this is right, too, ok?"
"Ok."
"So overall, you're doing the right thing of admitting although it ends up you being punished because you did not listen to what Teacher had said. Anyway, why your friend didn't admit? Maybe he's afraid of being punished. It's his choice. However, there is a fairy who is watching us, note down when we do the right things, when we do the wrong things. So keep doing the right things, ok?"

"Ok, Mommy. Hmmm... He shouldn't have lied... actually it's quite comfy standing facing the window because the wind blow on us..."
"???"
