We had this topic for Sims 3, and I have something for Sims 4 (or any of them, really).
...you have a dream like the following:
I'm standing in the doorway of the bathroom, and my brother goes down the hall and hands me a dirty plate. I think "I'll just do like the sims and wash this in the sink rather than going downstairs to the kitchen." I put the plate in the sink, turn on the water, and swish the water around. To my great surprise and disappointment, the plate does not disappear.
I woke up with a giggle.
