Homeless people appear and disapear randomly throughout society.
This accounts for the broad range of humanity that one can find in the "homeless" population.
In theory this happens at an even distribution,
it can happen to anybody equally... that means "good" people as well as "bad" people. It happens suddenly. The moment when all attempts at saving the situation have failed AND the person realizes they blew it. It is usualy comes as surprize to those so afflicted.
But then... after a time the "homelessness" wears off, one settles and works their way through and out, or whatever, the person "gets over it". But meanwhile "back at the ranch"... somewhere another homeless person appears. That is why there are so many different people.
A brief aside about the relativity of luck. An easy example is a broken leg that can spoil the plans of a rich man, or, finding twenty dollars when penniless and hungry and homeless. Which is the luckier of the two, the rich one or the poor one? Happiness and pain are relative and what you consider to be fortunate may not be so for the other guy, or gal. What if the broken leg got you out of a bad marriage or you spent the twenty on bad drugs and died, what then? Who's lucky?
Random events like the particles of gas contained in a balloon.
Statistically a certain number will impact on the interior surface at any given instant, then to be replaced by others an instant later... it is not indiviual atoms holding the balloon out, like little Dutch boys with a finger in the dyke. It is the random action of all of them.Homeless or not!
