	/*  The scenario for this Society is a bit more complex.
	 *	First, we have initially 6 Persons, three males and three females
	 *	Many things here happen randomly.
	 *	One of males (random) falls in love with some random female Person.
	 *	His love may be accepted or declined...
	 *	But in any case, finally one of our guys marries to one of our girls
	 *	(the process is random!...)
	 *	After they are married we get a new Person (new Object in our Society!).
	 *	It may be girl or boy.
	 *	And after we run a census. And we run it only one - at the end
	 *	(I believe you may guess what result would be if you uncomment line 39)
