On that one, it is not the trash can, but the bag of trash, and they could be standing right in a bran new place I just built for them, like, they move in, don't even get a chance to go inside, a neighbor comes along, they introduce themselves and she has the trash bag symbol over her head. I had wondered if she was thinking that the person she is talking to is trashy maybe? But, then again, those are not thought bubbles, they are actual chat bubbles, so, it doesn't seem like she would be telling a new acquaintance that he or she is trashy.
Too bad they didn't put out a log with all of the chat bubbles and thought bubbles in it for us
