Some questions

None of these are particularly rhetorical, but the first group is not for others to answer for me.

Why am I here? What am I doing? What am I useful for? What should I be doing? What do I want? What am I looking for? Why do I care? Do I want a partner? What for? What sort?

What are the precise and different meanings of e.g. i.e. a.b. etc. sic and ibid? What is the intellectual property status of a quote from a novel?
