Anyone who's been on Facebook for more than a few minutes knows there are a lot of unwritten rules.  MOST of you are pretty good about not breaking them.  But here's a little reminder for the rest of you.

1.  Only post the things your friends actually want to see, like mind-blowing facts and major life updates.

2.  Posts about religion, politics, or your workouts will get you BLOCKED.

3.  Never like your own posts.

4.  Everybody stalks . . . but don't get caught.  Liking photos that are already several years old is the easiest way to get caught.

5.  Don't have a conversation in the comments section.  That's what texting is for.

6.  Keep virtual PDA to a minimum.  Treat it like real-life PDA.

7.  Don't post every selfie you take.

8.  Don't make people guess what's bothering you.

9.  Don't invite friends to play all your online games.
