Thanks!
Now, to expand.
There's a theory on successful social interaction that the key is to be consistently witty and charming. This has generally been discredited, since being witty and or charming, even in short bursts, takes a whole lot of skill and a good portion of luck...and doing so consistently is completely out of the question.
The next theory is that since people mostly like to talk, the key to success is to listen. This works really well in the short term, but as has been pointed out after a while someone who just listens gets identified as creepy.
I said what I said, because I think the key is to remember that it is an almost universal state of mind. The other person won't think you are creepy if you do your share of talking, and they won't mind if you are not consistently witty and charming as long as you are talking about them. In some complimentary manner of course. Try it.
