Someone trying to force me to be their friend to the point of harassment, which has happened to me a few times in Real Life including within the last two weeks. They can't quite grasp you either hit it off or you don't. The more they try to force it, the more it's going to push me in the other direction.
And then trying to probe me with stuff that's none of their business. Even worse when they think they know me but don't know me at all.
That reminds me of the scene where Odo and Worf are having a conversation over the best way to discourage people from dropping by unannounced if at all.
Maybe you're too personable.
