A completely non-political bit of snark here. I absolutely hate it when I meet people who are bound and determined to be my friend. The less interest you show in them, the more they will hang around you and talk themselves up; they will know nothing about you, but still insist on being chummy pals. It's that last part that really drives me up a wall. If you want to be a friend of mine, it would be nice if it had something to do with me. Such people just cannot handle that there is someone in the world not particularly interested or impressed by them. The only reason such people are interested in me is because I am a human being who still has vital signs, ergo I must be their friend.
Screw that. And the worst part of it is, the normal disinterestedness that would indicate to most people you don't give a damn about them is precisely the thing that draws this sort back to you.
