Angpow from a 5yo

For Marcus Birthday, Shern actually took a AUD50 note from his safebox, put it in an angpow packet, sealed it and gave it to Marcus, all this without telling me. Well, I will be fuming mad if he gave the angpow to his friends or any strangers I don't know, but because he gave it to Marcus, I told him that it's good that he shares Marcus birthday joy and wanted Marcus to have something that belongs to him. But in the future, he so needs to tell me if he were to take any money from the safebox else he's so going to get smacking.

Good thing, I have all my 'treasure in the bank safe deposit, can't imagine him giving away my keepsake. Distributing gold coins in school, that's not even funny.
