Every now and then, I notice that I've lost a Facebook friend. It's not as if I obsess about the nunber of Facebook friends I have, but it's hard not to notice that number right there, prominent on your profile. One day it's x, the next day it's x-1.
I can never figure out who it was that dropped me, but I do wonder sometimes about the motivation. Did I post or say something in my status that offended someone? Did someone suddenly think "you know, I never really liked that guy, I don't know why I'm his Facebook friend"?
It's a mystery, no doubt. Not one that will keep me up at night, but a mystery nonetheless.
