The old man likes to smoke secretly how to do?

The old man has smoked all his life, and if it is mandatory for him to quit smoking, it will cause some harm to the old man both physically and mentally, and the only thing the children can do at this time is to help the old man control the amount of smoking.

Since the old man is secretly smoking, he knows that the children are against him. Since this is the case, it is better to spend more time with the old man and less time leaving her alone so that he doesn't have a chance to smoke. And with the family talking and laughing, the old man might also temporarily forget to smoke.
