HANDY HOUSEHOLD SIGNS

I use this sign for privacy. It seems to work among those who can read and are not too hotheaded to ignore it. For quiet Sunday afternoons.
This ones on the lid of my green bin so that I don’t come home and find recycling hasn’t taken it due to some oaf tossing a half-drunk smoothie cup with plastic straw into the contents, pretending they think it is a garbage can. While reycling has a point, how can you prevent someone throwing stuff on top of your carefully selected compost ingredients, other than with bear traps?
Finally this sign has been on my door for 15 years. It works on and off. Those with intellectual pretensions don’t seem to recognize what they are. However, you can solve many other problems with a good sign.
