Common Sense and Facebook don't mesh

I just don't understand why people don't understand that when they put things on Facebook or other Social Media sites that everyone will see and read it. Even if you have your privacy settings for "only friends" or "only family" because someone in the group will tell, share or re-post your post. I don't get why they complain that their boss,neighbor,classmate and associate end whatever relationship they have with them. There is a reason its called Social Media. Really people if you call your boss names or post yourself getting hammered with no clothes on or making out with your neighbors boy/girlfriend what did you think would happen? That they would give critic on your making out skills? Give you a raise or promotion? Get upset because parents complain to your boss that they don't want someone that does drugs while humping someones leg half dressed? You're surprised? Really? I think that a lot of people lack common sense. They may be intelligent people and have this or that degree but when it comes to common sense, they do not have any at all.
    I was trolling around and I seen this post that when I read it I thought it was a teenager. So I checked the profile and it was 38 year old woman. Is it a side effect of using Facebook that you revert back to puberty? I have to admit I like to play a couple of those games on Facebook. I joined a group that was for that game. Mainly for finding "neighbors" and help for the game. I was on there today and good grief they were cursing each other because someone apparently did something on their land when they were visited. The way they were going on you would think that someone had stole their husband, drained their bank account, sent compromising pictures to their boss and burnt their house down. I quickly left that group. Oh well I better go and check in on Facebook ....
