"Just nod and smile"

I have a student in my class that is very easily excited. When this student gets worked up it is sometimes hard to understand what he is saying. Today when we were at breakfast something happened (I still don't know what) and he was SO excited! He shouted something, and I kind of looked at another little girl in the class who was sitting by him to see if maybe she understood what he said. She realized I was a little confused, and I was looking to her for a little explanation. She very lovingly looked at me, and with the wisdom that only a 6 year old could have, stated, "Just nod and smile, Ms. Guinn... Just nod and smile."
