MH, whiteboard? LOL No way. I don’t need a reminder of all the **** I haven’t done. Being nagged at by an inanimate object is not what I want to happen when I go into the kitchen to grab a beer before lazing on the sofa to watch the hockey game.
I have another household in my family who does it. They use it as a shopping list. When you see a certain food run out or you think of something you add it to the board.
But the thing is you can't bring a board to the grocery store. I think a magnetized paper pad and pen on the fridge might be more convenient.
I agree with you that I don't want chores on my fridge.
