as plain as daylight; as plain as the nose in your face

1. 現在你把此人與他妻子的關系告訴了我，這樣，整個情況就一清二楚了。
   Now that you tell me about the man's relationship with his wife, the whole picture falls into place.
2. 當我們的意見有分歧的時候，邏輯只會搞亂妻子的腦子而已：她不是為了反對那一清二楚的事實而爭辯，只是為了反對我而反對我??！
   Logic merely distracts my wife when we disagree: it isn't the clear-cut fact she's arguing with, but me!
