Yep. People are quick to raise the "well if you can't talk to them without Facebook they aren't real friends" argument but fail to realize it is entirely normal to have acquaintances or relationships with people without them being your close friends, at least for those in the younger age groups (20s?). I'm actually not on Facebook but that was a big downside of leaving the platform when I did (i.e. when people my age actually used it).
