昨天子峻被校长冤枉推到班上一位女生。是不是因为你留给他们的玩皮形象? You are punished by standing outside the class and you accepted it & we guess it's becos that's the common punishment you have when you misbehaved. Mummy got to know yesterday evening when we fetch you from school & I absorbed the whole incident quite lightheartedly. But today, I kept thinking and imagine you taking the punishment yesterday.. these questions kept flashing into my mind ; how come you did not inform teacher, explain to them or insisted you did not push the girl. 五岁的你会解释吗?It is not serious matter but we felt unfair you suffer the blame wrongly. 想一想,其实玩皮与坏蛋要客观的判断 。。我希望这件事不会对子峻有太大的影响。
