hard feelings 怨气
A: Man, I'm really sorry about what happened last night.
A: 老兄啊! 昨晚的事真是抱歉..
B: It's all right. It's over with. No hard feelings.
B: 没关系。已经过去了。没什么好生气了。
"It's over with" 是'已经过去了'。结束某种不愉快的情绪, 可以用 'get over'。 如 "I know you were mad at him for what he had done. But, it has been five years. Get over it."
我知道你很气他所作的事, 但是这已经是五年前的事了, 你应该释怀了。
