But that's what real-life is like. In most social situations, people are not going to tell you what they hate about you. This is as uncomfortable for them as it is for you.

As someone who was once friendless and unpopular, I agree that this is crazily frustrating. But it is the way it is for a reason; it is rarely a productive or pleasant use of time for someone to tell someone else why he sucks. If you're on the friendless and unpopular side, it's up to you to observe carefully and watch why some people are popular and some are unpopular.
