Most of your friends on Facebook aren't really your friends. They added you so they would have a lot of friends on Facebook. Some people think that its a competition to see who has the most friends. What they don't realize is that in reality, thye don't have any friends at all.
When you try to be friends with everybody, you're friends with nobody. Instead of getting to know someone personally, you know so little of the many people you interact with. One of my friends said to me "Facebook is like high school. The most popular people in high school are the same ones who get the most likes. I put a status up and got a couple of likes. This girl who was very popular in high school got a lot of likes. Facebook is the continuation of high school.
I want to say that my friends aren't like that, but I'd be lying. Most people do this subconciously. There are people who break this pattern, but they are outnumbered by the mindless members of facebook. Too bad nobody graduates from Facebook though. You can try to choose better friends but it sucks meeting a person you deleted on Facebook. I remember when I deleted some kid on Facebook and he sent me another friend request. He was in my math class but we never talked. I don't even know why I added him in the first place. He sent me another friend request and I denied and and the next day he sent me another request. He really wanted me as a friend because he was trying harder than a car salesman. In class, he never said it word to me. I was confused, so I did the only thing left to do: block him. He had a lot of friends, close to 1000. I'll bet anything he doesn't even talk to 75 percent of those people.
