For those of my generation who do not and cannot comprehend why facebook exists: I am trying to make friends outside of facebook while applying the same principles.
Every day I walk down the street and tell passers by what I have eaten, how I feel at the moment, what I have done the night before, what I'll do later and with whom.
I give them photos of my family, my dog, and of me gardening, taking things apart in the garage, watering the lawn, standing in front of landmarks, driving around town, having lunch and doing what anybody and everybody does every day.
I also listen to their conversations, give them the "thumbs up" and tell them I like them.
And it works just like facebook! I already have four people following me: 2 police officers, a private investigator and a psychiatrist.
