From an adult child who does not live at home any more:
"All of you are starting to drive her crazy again. She's putting her signs up!"
There is a measure of truth to that. There will be signs going up on how to be a good housemate in the kitchen, bathroom, and laundry room. A polite note in view is more effective and more efficient than verbally reminding multiple family members and keeping track of which ones I've reminded.
