Awkwardness, shyness, embarrassment and inarticulacy are as much a barrier to communication as lack of concepts. It may well be possible to describe a complex situation in a fluent and competent way. But if the situation is stressful and the communicator is young, then the 'possible' fluent description is simply not available, so communication does not take place. That makes things even more stressful. Add to that the very important consideration that the other party does not seem willing to listen at all. It may be theoretically possible to make fine speeches but if the other party is not listening, the fine speeches have little communication value.
It is for all these reasons that the youth code has a direct and immediate value. To be able to sum up a complex emotional situation in a single code is useful. Unlike situations where the code is a convenience, the youth code may be a necessity.

Obviously the code works best if both sides are fully aware of it. Therefore there have to be advantages for both sides to encourage a willingness to use the code.

If only one side is willing to use the code, then the code can still be used as a supplement to other communication. In time at least some of the items on the code will be learned through repetition. There is certainly nothing to be lost by using the code. The time taken is tiny. The potential benefits are huge.

The code would normally be used from parents to children or the other way around. It could also be used in any adult-to-youth or youth-to-adult situation.
