我觉得你要把DEAN的原话拿出来才好判断。

这个是怎么说的：“被DEAN问是不是拿了A的BINDER”是did you take? or did you
see? if he used TAKE, you should think about demanding an apology. if he
used SEE, then it is ok. and ” 说你们可以看看我的BINDERS“ is your son's
offer which i think was not necessary.
别郁闷，先搞清楚事情再说。如果他用SEE， 你可到学校COMPLAIN下。别让孩子受
委屈。
