One way to tell if someone has no friends is that they always have to initiate get-togethers and even then, it's spotty. They may have a group of friends whom they have known for a while, but those friends don't call or email them really, and only have fun when the person with no friends rallies everyone together. This pattern can be troubling and make the person think that they are doing something wrong. The fact that this is a pattern in all their friendships is a sign that something is amiss. They may be able to chat with people around the neighborhood, but then nothing comes of it, and others get together without them. They may have family members who are great, but they never call or ask to get together, and it always has to be the person with no friends who initiates contact. Temperament, insecurity, and preference can be barriers that create distance between the person and others. Psychological issues, lack of experience, and situational obstacles can also contribute to the person's difficulty in making and maintaining friendships.
