Only Sinkie losers who are born losers need give their parents money...every month.
Your parents if they were NOT losers would have retired with millions. And what would these 'monthly petty cash' be of shit worth?
As a matter of fact, Sinkie who were NOT from losers family would expect a BIG windfall upon their parents passing not to mention the occasional 'leg up' they will provide while they are alive.
This would set you thinking ...HOW THE FUCK did some young upstart Sinkie get overseas IVY League degree comes back and buy landed property, owns a few cars and never seem to need to give their parents...
monthly petty cash ! LoL
