Getting my nails done

so i went and got my nails done and the lady that does my nails was telling me about one of her clients has lung cancer. She smoked like 25 years ago and now they have found lung cancer it is terminal. So she keep on going on and on about the dangers of smoking. I know the dangers of smoking kinda. But i am sure that she knows that i smoke it isn't like i hide it but it was just strange to hear her talk about this. I know that she was just trying to help but i found it uncomfortable.
