What would it take for a double T on a 13 year old boy?

[coach mb]

I searched the forum for "technical" and found some interesting reading. Tolerance, warnings, sure ways to get one. But one thing is for sure, the majority of the officials would rather NOT give a T "if" it can be avoided.
Here's a situation that I was made aware of. I was not there. I'm the league director and received a call from the ref and coach of the boy getting the double T.
7th & 8th grade boys. Close game (a few points). Player gets his 5th foul (ref A making the call) and reacts by raising his hands and has some audible words (no swearing). Ref B hits him with the first T. Now here's where the stories differ. However, after talking to 4 people that were there, no one is saying anything worse happened ... just more mouth and yes, a second T from ref B.
Question, at this level, what would you do? Is a second T justified? After the first, would you signal the coach to control his player? Warn the boy that he's about to get a double and ejection? Or just T him again and hope he learns a lesson.
