I can definitely emphasis, although I think I'm just a bti tired at the moment, and therefore not really energised or connected.
I don't think from initial meetings people expect very much, except to gague basic personalitiy traits. If you were a arrogant arse, then I guess that would become apparent within the first few minuets. The majority of exchanges are snapshots, and fragments which serve short term purposes.
mmm... now that I'm thinking about it, I don't really know how you move from the initial introduction to something longer. I guess it really depends on where you are at the time. If for example, you're just about to go into a class, that conversation will not go anywhere, but if you're in a bar, or at dinner where everything's more relaxed, then it's easy to go deeper. If you discover that you have something in common with that person, perhaps you could suggest doing something related together, and then get to know them more through that?
