My seven year old was looking at some (commonwealth) coins and asked who the lady (queen elizabeth II) was on the back. I asked who they thought it was, first guess was "Is it Siri?"
The second guess was "Is it Grandma?" but that was definately a bit of a joke. Just not many other candidates they could come up with for lady of prominence that would make it on a coin.
Interesting!
Did you learn why?
