Gotta raise 'em right: get up when a lady enters, hold the door, say sir and ma'am, follow the four rules.
This kid also has been raised with a strong sense of confidence in his actions, evidenced through proactively checking for all shooters - regardless of age, experience, etc - to have hearing gear on and checked to make sure that everyone knew that the range was "going hot".
This is a parent (likely, parentS) who have raised their child by doing some things right.
The real trick is to see if this same child acts up in class or runs amok in the neighborhood.
He's doing things perfectly on the range. Let's all pray that he's as good in public as well.
