赞同! 下午给老师发了个email，晚上收到了回信儿。回信在这儿。父母和老师共同协调吧。谢谢众亲!

I totally understand your concern, that is not acceptable behavior in my eyes. I will make sure to address the situation with both boys tomorrow, and I will pull xxxx(my son) aside to talk to him about it privately, too. We always talk freely about standing up for yourself in class, so I will make sure to readdress this issue tomorrow with everyone. Thanks for letting me know!
