Yes, today i am angry and sad. There's nothing odd about that.
But another thing. Facebook , blogs and other alter ego creating machinery. They help us to present another myself. Happier, prettier, smarter, crazier -anythingier...
Suddenly it seems so boring. But a second passes and i think-who wants to see other people just as they are. Another second passes-well, we are never the same on the outside as we feel inside. Most of the times it's even impossible to project yourself.
All the literature on this particular subject!
It could be that the bouquet of photos, quotes, words and many other things posted on internet help to create an image of you that is closer to what you are or what you want to seem like (tells a lot about you anyway)than spoken language or written diary.
Spoken and written language is guilty of many things. Try to imagine us without it. Where would evolution have brought us to without the use of this monster? Telepathy may be? Or a long tail and large ears to improve the body language based communication?
