Because with 5 people in the house having hot drinks, yogurts etc and a not unlimited supply of teaspoons, I frequently find them all languishing in the sink by mid afternoon where I have to fish them out and rinse one (now I need a special rest for it!). We usually only wash up once a day, probably not alone in that.
Ours get a rest in the dishwasher, if there's none left in the drawer then we just wash one. If anyone leaves one in the sink then I hunt the culprit down. No dishes get left in or near the sink, dishwasher or wash it and put it away.
Teabags rest in the teapot until cold.
