When I was very young, Auntie Audree was living in the US.

On my birthday, she used to send across some money. It was one of the highlights of my birthday, receiving some US dollars and the excitement of figuring out the exchange rate and whether it'd be worth more or less that the number of dollars ;)

It brings a smile to my face every time I think of this and everytime I have US dollars, I think of her.
