man: hey man i just talked to you. but you seem to be absent-minded. whatever i say to you goes in one ear and out the other. oh man you are nuts.
woman: oh i am sorry because i stayed all night for perparing my testing yesterday night, that is why i am really absent-minded, i hope you never mind and am just a little rusty you know.
man: ok i forgive you but i don't want to look like this thing happened again
woman: yes sir

Question 1: why did man say that you are nuts?  
Question 2: what dese woman do at night?

no choice , this question is over my head , i hope some people can help me slove my question. thanks a lot.

answer 1: because the man have no comman sense

answer 2: the woman will prepare her test for tomorrow.

Q1: you are nuts means you are crazy

Q2: The woman guarantee that she would not do the same thing tomorrow.

这种对话能考吗？ nuts这种骂人的词，这两个人的关系是什么啊？ 男的如果是女的上级之类的人怎么可能这样说话阿？
