Everybody just wants to earn fast money. Her own greed betrayed herself or financial consultant lied to her making her so addicted to buying gold shares. She doesn't want to believe the fact she's lost so much money. That's why she repeats what she's doing now.
Human have became so greedy and heartless, stealing elderly money despite knowing the lady has refinanced and borrowed money everywhere. I hope you able to find your peace in 18th level HELL. Go hell Mr Cheuk and Henry.
