15 years difference used to be a maximum gap, before the revelation of "Net Generation", which, i title as "NGEN's".
NGEN's made the information that is available out there, to be available in here, inside the house, through a tiny screen. The exposure of general mass has been increasing ever since, everyone knows anything at anytime. And here come the individuality of a single human.
Individuality has made the criteria of building a relation goes in parity with our aspiration and little worlds. yes, everyone has his a her little own worlds. this has made the maximum difference relatively increases, and i believe it is 7 or 8 years at max. the less the better, the more the gap the more the problems.
