If you want to waste your time, fair enough, but don't waste mine too.如果你想浪费时间，很好，但不要也浪费我的时间。All this is fair enough, but it is only one part of the story.所有这些都不错，可是这不过是事情的一面。If you don't like it, fair enough, but that's hardly a justification to attack the whole thing.如果你不喜欢，这说得过去，但把它批得一无是处就没什么道理了。
