Oh, my friends and how convoluted we are.

1 dated 2.
1 dated 3.
3 dated 4.
4 dated 1.
1, 4, and 5 lived together.
5 moved out to live with 3.
2, 6, and 7 lived together.
2 moved out, 8 moved in.
8 replaced 5 as 3’s roommate.
6, 4, and 5 moved in together.
7 replaced 5 as roommate.
1 replaced 3 as 8’s roommate.
5 crashed on 1 and 8’s couch for a few months.
Now 7, 6, and 4 are going to rent from 8 and 1’s landlord.

That’s not even counting the sex.
