ok i'll keep in mind not to use じゃないです and/or じゃありません. regarding the third question, after Bob says 図書館は, can Alice reply this:　図書館も行かなかった?

Also can のに be used with only the left part of the sentence as such: 金持ちのに


From TaeKim's guide he provided an example マトリックスを見たけど、面白かった which translates to "I watched the Matrix and it was interesting". I was wondering if けど could mean both "and" and "but", how exactly should we decide what is it supposed to mean.


As for the sentence なんで友達に会う時間がない, is it true that it can either mean both "why is there no time to meet friend?" and "that is why there is no time to meet friend"
