invisibility on society?

I take it that you mean that someone is sort of invisible in society, i.e. isn't recognized by other people or society as such.

To me it's obvious that it happens when someone, for some reason, abandons his or her social position. For instance they may lose their job, get divorced or get evicted from their home. These people are invisible, at least to a certain degree, as they are no longer tax payer although they may be in debt

invisibilty is produced with the force field. you see the light she is like the water. the force field will part the light just like the water. of course the light switch will produce the invisible also. the problem with the invisible is the light does not bounce off so it makes the person into a black spot. the cops come and they use a night stick on the black spot. it is very difficult.
