Blocking your relatives
Your mom’s on Facebook, dude. Deal with it. She thinks it's lovely and enjoys all the nice videos of baby elephants. If you’re still worried about your family seeing your posts (on an online public forum), maybe it's time to rethink the stuff you're into. Unless you are a furry. Then please go ahead and block your parents. They don't want to see that. Actually, block me, too.
Father always said, "Pretend like anything you are posting on the Internet will be on the front page of tomorrow's newspaper." With Facebook, this is actually kind of our reality now (sorry for laughing at you, Pops). So please, keep bodily functions, diseases, sexual habits, fetishes, gruesome injuries, and dirty secrets to yourself. Or at the very least, to Instagram. #NoFilter.
