No need to apologize, Lara. I do like FB for keeping tabs on friends, but I’ve been pretty good about not letting it be a time suck (I usually just scan it on my phone), and I also don’t let it replace in-person contact. I primarily use it for keeping tabs on old friends who I otherwise wouldn’t talk to (college fraternity brothers, law school friends, etc.), but who I’m very happy to hear from and see what they’re up to.
