I just love, love, love the fact that you or one of your Facebook friends can just disappear in the middle of a back-and-forth thread and no one gets offended.
You have the freedom to ignore what you want to ignore, engage with what you want to engage with, without anyone asking you to explain yourself. And even if they do, you’re not obliged to answer. Maybe you were offline, maybe you were having dinner, whatever! Hard to get away with this in the “real” world!
Do you get offended or worry when your friends disappear from Facebook for awhile or don’t respond to your posts?
