Remember when you and indeed all of us were still heavily indoctrinated? Remember what we all were like when we heard of a special talk being given? We were always thinking, is this it? Now put yourself in your mother-in-laws shoes.
The difference being, your awake and your mother-in-law is still under the mind control, every announcment of a special talk is usually followed by active JW's thinking and saying this is THE talk. Probably more details in the "new light"
