I'm an E4--always have tested as E4, and a friend who teaches Enneagram classes just said, right after I met her, "Ah, you're a four." But I have never been able to figure out a wing for myself. On various tests I come out with slightly higher 5, slightly higher 3, or equal 5 and 3. But I score higher on 7 than on either 3 or 5. On some tests my 7 score is almost as high as my 4 score.
Is it possible to really not have a wing? Or am I missing something? Please clue me in.
ETA: I bugged people in chat today for information on figuring out my instinct stacking, and via that help it appears to be either sx/so/sp OR so/sx/sp.
