I think some of the smaller, repeating bonuses for Happiness or a small gold amount (1-5 gold) should have a slightly longer continuation - like if you pet Boots' belly enough, he goes and keeps the streets clear of rodents, raising happiness by a larger amount, or if when you pet Pancakes, there's a slight chance something will happen from the slightly magical cat - perhaps even the ghost who inquires about the castle being a castle return and offer a small gift as a way of apology for his lack of manners, getting gold if you accept, happiness if you decline.
