There are a handful of people on my FL who aren't around for various reasons. Most of them have been with me here for a LONG time but that shouldn't be a reason for keeping someone. Neither should the fact that I consider them to be close friends. Some people can keep up on LJ and FB, others would just rather use FB. And that's fine.
Should any of you decide to come back to LJ, I would welcome you back here in a heartbeat. ♥
