@Morumotto  I'd say otherwise, its just every country has unique familly customs. If anything, his father is just concerned hence pressures him to get a stable paying job and not just rely on risky stock market. And lastly the parents seems already wealthy and successful to just gamble and leisurely spends their remaining time.

you stupid fûck
