FLOCKED.
The answer for the friends-onlyness is simple. I am afraid of ROBOTS and the powers that they hold. See, a lot of ROBOTS were friending me, and while I realize that it's unlikely that they read my journal, it made me afraid that they were stalking me in order to assassinate me, so I've FLOCKED it.
IF YOU WANT TO BE MY FRIEND, COMMENT TO PROVE THAT YOU ARE HUMAN, AND THEN ME AND YOU CAN BE BFFLs BECAUSE I ENJOY HUMANS.
