I must say that it was a problem for me during my own teaching, or rather I did not follow this rule very much and addressed the boy. However, I feel that he reacted positively, cooperated and after an hour, when everyone was gone, he still wanted to write an unfinished exercise in his notebook and then talked to me about how he is still learning Hungarian. So far, I've only been listening to six-year-olds. They are taught by another teacher, who is also very nice and in the class she is clearly full of positive energy, which is perceived by children.
