My wife's expressions

My wife Natalie likes to interject interesting and poetic lines to punctuate her speech. Here are two recent examples:

"Well Joe, you can't contain fire in a paper sack".

and

"There was a famous Chinese general who led his men to a decisive battle across a powerful river. When they arrived he immediately had all the boats burned. This way, the men knew they must fight and win, since retreat was no longer an option".

She'll just casually throw these little sayings and stories into our conversation. She makes them up, but they sound like they're from a book. I love that.
