When MySpace and Facebook first showed up I was really open and I overshared.
After a while, I felt like it became too crazy and now I'm extremely private. I just have the most basic information on my profile and links to articles mentioning my work.
I'm really extroverted and open socially, about the way I view the world, my opinion on things and stuff like that, but I'm extremely private about my personal life, my history and my feelings, like... sometimes I don't even trust my parents. I treat my mind and my soul as a sacred place.
My (our) generation is judgemental to the point of insanity, tbh. I remember in school how absolutely anything could be deemed uncool or awkward or embarrassing, etc, and so I'm definitely a private person.
