Hi Chuanchuan,You can try rephase all the questions to your favour, for instance:Mum: Which shirt will you like to wear, green or blue? This way, if your son wishes to ans either of them are ok for you. There’s no need to tell your son that it is clean.He is just starting his N1 class so there maybe some regular situations that he feels frustrated at the centre yet he does not know how to express. You can discuss this with his teacher.
