“We can be poor in spirit, and I don’t even consider myself wealthy, which is an interesting thing, it can be here today and gone tomorrow” -Ann Romney on Fox News
It can be here today and gone tomorrow. Amazingly cavalier.
For the average person "here today, gone tomorrow" refers to being one medical emergency away from bankruptcy, or one car repair away from eating Ramen noodles.
For the Romneys, who are worth roughly $250 million dollars, "here today, gone tomorrow" takes on an entirely different connotation.
