I've been playing a wonderful conversational game of late, having generic conversations. The game works a little like this, instead of having an actual conversation, you express the generic underlying conversation or make vague, general statements. It's a little hard to grasp from that description, so here's an example.
A: Statement of inquiry.
B: Acknowledgment of inquiry. Vague half-answer meant to divert topic.
A: Statement drawing focus to diversion but accepting it and changing topic.
C: Bold statement regarding new topic meant to draw attention to self.
B: Veiled statement of distaste for forceful interjection. Empty statement to lighten conversation.
A: Witty banter.
C: Short joke that's not very good.
A: Really terribly joke.
B: Statement about a current event.
Of course, this is a poor example because I had to come up with it on my own to illustrate a point. Certainly though, one can use varying levels of vagueness and generality. It's a great deal of fun and can be rather challenging to keep things generic but interesting without repeating oneself or devolving into meaninglessness.
