When I am in public places I watch people.
It is amazing to me how seamless they interact with each other. To me, they look fake.and needy.
Yet, observing for an elongated time (school gate, for example) you see how the seamless interacting also makes them very efficient, once something community based needs to be done. Organising seems to go automatically, and nearly flawless.
When standing at school gates you can observe a similar thing to what is happening on the school playground. There are groups of popular and less popular people. And, there are the misfits, standing outside the groups, but, now and then interacting with each other, in a totally different way than the groups.
Very funny when a tall symmetrical person of the opposite sex arrives, btw. Very funny.
Watching people is a good pass time.
