Words describing types of conversation

I have three related questions, all concerning words descriptive of conversational habits.

(1) How would you choose a word to describe someone who likes to talk about things around them and things happening in their whereabouts?

[The opposite of absent minded]

Actually, absent minded though would not do a very good job at describing someone who likes to talk/think, perhaps not on their own, about abstract things or things they imagine).

(2) And how would you choose a word for someone who likes to talk about things happening elsewhere?

(3) And how would you choose a word for describing someone who likes to talk about the past?
