Good she told someone. I remember one incident narrated by my collegue. So this colleague got engaged and was about to get married. Her mommy passed away due to cardiac arrest just a couple of months before her wedding. This colleague visited their family jeweller to buy something. Then he asked your mom ordered a big necklace ,paid for it and never came to pick it up. That's when they realised that her mom from her secret amount (maybe stored in asafotida box) has ordered the necklace. For whatever reasons she didn't inform even hubby and kids. Jeweller was a gentleman . He gave them the necklace. Sometimes just in case something happens we never know. It's okay to have a secret account. But sharing the secret with someone is required.
