I have a very similar job but more more like 1/4 billi lol, but same concept. Not a chance I wouldn’t know or figure out who is who. 

Aside from what you already shared, my boss is genuinely thoughtful and kind. She’d never have me send a gift to something and not acknowledge it herself or write a card. Bad life tip lol

Same but with a 1/3 billionaire who is neither thoughtful nor kind.  I wouldn’t send a random gift to someone I didn’t know lol
