The first picture is a sticky note attached to the water dispenser on the refrigerator. The buttons are confusing, so we had to add a sticky to explain how to get water and ice from the machine.
The second picture is a dog gate meant to be used to block them from going room-to-room, but instead of using it for that, we put it so that the dogs couldn’t go down the stairs into the basement.
Finally, we again used sticky notes to remind people the water the plant occasionally. As you can see by its withering state, it was not very effective. There is definitely room for innovation here with finding ways to automate the watering process, perhaps through a small irrigation system.
