At this point of time, yours truly was startled and was wondering how yy would react. So guess what yy did.
Yy got out of his car and raised his fist and punched the air a couple of times letting of his anger. He did not once hit the bully! On one hand, we are glad that he had good anger management but on the other hand, we're not too sure if that's the right way to handle bullies... We made up our minds then to make sure that we send yy for martial arts training when he gets older...
