Children more likely to have frenemies than enemies.

This recent article from Science News discusses relationships amongst elementary school children.

Kids' friendships sometimes illusory: Surprisingly often, grade-schoolers say they're tight with a peer who actually dislikes them.

In the brutal social world of elementary school, friendship can be deceptive. It’s relatively common for children to consider as a friend a classmate who admits disliking them but seems affable on the surface, researchers say.

Other children feel they have friendships with children who have no opinion of them at all. Sounds like a lot of adults I know, wonder where they learn this behavior?
