You shouldn't feel abnormal at all :P
In fact you should feel amazing! In a society where people have become slaves to social media and smartphones, you are one of a few people who have managed to escape this plague.
Social Media and Smartphones, or as i call them handheld computers have completely ruined society. People are so delusional, always seeking attention, appraisal, looking for that red notification, for that dopamine rush. Just like morpheus in the Matrix, dont look at the woman in the red dress, its all an illusion, a trap, a government program to get every record of every human on the planet.
Just think, back in the good ol internet days, you had forms of social media, which allowed for any sort of username, yeah back when people had creativity , or back when the internet was a place for creative people, you could have whatever picture, background colour you name it.
Facebook is a very dull site, you cant change the ugly white grey blue background, cant change the font, you cant add a custom cool image as a banner, you HAVE to have your real name and Real Address..just think how wrong this is! This is absolutely sickening, that they are getting away with this, but think of how many people have signed up for an account..its insane.
Facebook is also a very depressing site , because of the lack of colour, vibrance and personality..every comment is a person "tagging" some other person, to some internet meme, or something overly used and mainstream. Theres no intelligence or anything involved, its a game of popularity and people are competing with one another to get more red numbers than their friend, or more mentions in photos...think what a horrible generation this is, where people nowadays rely on this as a norm of socialising..gone are the innocent days of sharing experiences with just your friends, or by actually talking face to face.
Facebook together with Smartphones/handheld glued computers = destruction RIP society.
If i were you I would NEVER create an account there, dont degrade yourself and become one of their sheep. You are clever enough not to have one already, if my university wasnt reliant on facebook for updates i would delete that **** right away.
