Come on, why don't you get me?

This morning in Peter's class, i was trying to sit down on the mat while waiting for Yaya putting Peter's jacket away. Unexpectedly, Peter walked out from my arms and towards his teacher, with his arms wide open. In the meantime, he was talking to his teacher with a rising tone, like"Hi, why don't you open your arms and get me here?" We were all laughing and I left knowing my son really begins to get used to the drop-off routine.
