Yes, I'm saying that inferring the information from the chat transcripts is unforeseeable to the users generating those transcripts. It's obviously foreseeable that if you change your relationship status to "engaged," you might begin to see advertisements for wedding-related stuff. Perhaps a better situation to illustrate the point is where a girlfriend is talking with her friends that she's hoping her boyfriend will propose to her soon. That boyfriend, based on the information in the chat logs, might begin seeing advertisements for engagement rings. Those are the types of inferences that I consider unforeseeable.
