Sorry, I couldn't help overhearing, did you mention something about...
对不起,我无意中听到你们的谈话,你们是不是提到...
Yes, I'm sorry about that. I think we just had a misunderstanding about the plan, but I was very disappointed not to be going out. So I got angry and started shouting at you.
是的,那件事我很抱歉。我想我们只是对于外出计划有误解罢了,不过没能外出我很失望。所以我就生气了,开始冲你大喊大叫。
