If you don't get married, then someday this relationship will
end. If you get married and no kids due to sg's high cost of
living, the marriage will end in divorce someday. So to fulfill the
universal law of life, get married must have kids. No kidding.
Even if this happens, People still keep pets as subsitute for
kids and treat them like how they treat their children. Just that
they are evading the responsibility to have a real flesh and blood
coming out of their hole.
