person A: I am constantly finding plates with food or grease still on them.
person B: That is annoying!  Is someone in your house not doing there job cleaning after themselves.
person A: No_comma_ they think they are but I guess they are lazy and don't use soap on their dishes or will just dust the plate off and put it in the drain! lol
person B: That is no good.  What are you going to do about it?
