I love seeing "Post No Bills"
Reminds me of the childhood days when I didn't know that a "bill" was a paper sign announcing an event. But I knew "post" was a synonym for "mail".
So whenever I saw "Post No Bills", I thought it was a call to action for companies not to send the electric bill, the credit card bill, the water bill... which made sense to me.
Bills are stressful.
Bills take money.
Bills cause fights between loved ones.
Down with Bills! Post No Bills!
"Post No Bills" to me meant "Let's Have a Peaceful Barter System"
It's still a worthy cause. I just wish it was still a revolutionary sign for me.
