Grammar Point - Why Not In Chinese "怎么不“

Another Interesting grammar point. We use this structure a lot in English when making a suggestion in the present tense. We could say, "Why don't you go to sleep?" I learned how to say this in Chinese.  

e.x. Why Not? 怎么不 - (zen3 me bu4)

Why doesn't he come to work?
​ 他怎么不来上班？　

We could even take a step forward and use this in the past tense? Instead of saying, "怎么不". you should say, "怎么没" (zen3 me mei2)

E.x. 

Why haven't you slept? - 你怎么没睡觉？
(Ni3 zen3 me mei2 shui4 jiao4)
