20 years ago, she went to the commercial bank to get money which was very huge amount. The bank told her, she was not allowed to take the money as the Central bank needs her to declare it where the money came from and why etc.
After few days, the money was transferred to her account. The bank gave her the transferred slip together with the note written "Gift from son" which the bank made it easier for her. And the real message on the note that came with the slip was written "Everything I do, I do it for you" from your son, somewhere in Tokyo.
That was the best love story between mom and son I ever heard.
