I don't think that'll work. People can have more friends than just two. They can even share more friends than 2.

For example, A is befriended with B, which is befriended with C and E, where C is befriended with D, and D befriended with A (the original circle), but E is also befriended with F which in turn is befriended with A.

So there's 2 circles of friends, and A and B are in both: A-B-C-D-A and A-B-E-F-A.
