I'm often irritated when I see photos of happy friends at birthdays etc on Facebook. People don't seem to share the downs as much as the ups here. Although no one likes a wet blanket friendship does mean sharing the good with the bad.
Is Facebook making us more optimistic? I don't think so. Our editing skills are improving definitely. We may not be happier but by choosing to only share our high points we are projecting illusions. These are only part of the truth.
Would any purpose be served by status updates which moan, grumble, and seek reassurance? Maybe not. Facebook is not a personal newspaper, it is an advertisement. You don't objectively report the good, bad, and ugly in your life.
You try to sell your life to others and yourself. Look at the fun I'm having! See how wide I'm smiling! Rather than candid photography, it seems posed. A Polaroid which gets instant reactions. Ironically half the time the people who react to our updates are the ones to whom we are supposedly close.
The real conversations happen offline, where we share our desires, dreams, and fears. I too like posting happy updates. If I don't post one for a while I wonder whether my life has become unexciting.
But life is like that. Chronos lasts longer than kairos. We would get tired if we were cutting cakes, dancing, or climbing mountains all the time:) So let's not forget Facebook's our movie, offline's our reality to which we return when we finish watching pictures of others' lives.
