On 14.01.2019. the 5th.A and 5th.B grade students held a non-standard lesson on the theme "Can I say" NO! "?". Moderators of the training were Nadezhda Raychinova, Plamena Boneva and Tanya Ilieva from the Center for Public Support - Karlovo. The lesson began with a presentation on aggression, continued with a talk on behavioral patterns and techniques to deal with aggression. The students took part in role-playing games to resolve conflicts without violence and were convinced that a friendly hand, a good word, and resolving the argument with patience are good enough.
