We have all done it.

You meet someone in a class or at a party and the second you get home you look them up on Facebook.

You check their relationship status, look at their pictures and mutual friends and find out as many details about them before you have known each other for more than 24 hours.

It is awkward knowing that someone you barely know could know every detail about your life, like what bands you like or what religion you practice.

They read comments on your page and your statuses pop up on their newsfeed.

The worst part is that you don’t know who is looking at your page over and over again.

Three types of Facebook creepers exist.

The first kind is the closet creeper.

This person doesn’t want you to know they are looking at your page. He or she will look you up but not friend request you until a few days or weeks after meeting you.

They want full access to your page, but they don’t want to seem desperate for your friendship.

They also won’t accept a friend request right away if they get one, because they want you to think they are too busy to be on Facebook.

The second kind is the careless creeper.

This person adds you on their iPhone about three minutes after meeting you.

They do not care if you know they are a Facebook addict.

They comment on every picture you have and chat you constantly.

These are the annoying ones.

The last kind is the stalker creeper.

This Facebook creeper not only looks you up on their own, they ask their friends to look you up and use their accounts to look at your page.

This is the most extreme form of Facebook creeping.

It is borderline stalker.

Along with people that creep on your page, people will also want you to look at theirs. They want you to know what they are doing all the time and post every little detail of their life.

If you are running on four hours of sleep and are exhausted, maybe you should log off Facebook and take a nap rather than updating your status every 25 minutes.

I’m not saying that every person is addicted to Facebook or spies on their friends all the time, but it is a pretty common occurrence that makes you wonder: Who knows your life story?
