I have upped my game! The lovely (and probably not grumpy) Becky Higgins shared a cute "no doorbell" sign. (which would be helpful, but the dogs will wake up any baby within a 10 block radius with a knock too) And below, I found this little No Soliciting treasure.
You bet your sweet Gymbucks I printed that sucker off. Not only that- I LAMINATED IT. Then promptly pasted it to my door:
That's just how I roll.
