 When your son starts smoking, you don't know until he's grown. You know the reason why? You lack the capacity to discern that he has changed. No, he has started smoking long ago. Madam, you were telling us last Saturday. See, the person said, no, it's a bad company. No, he asked the boy. Since when did you start? He said, what, secondary school? Do you know what was the problem? The father was absent. The mother was absent. Not that they are not present. They lack knowledge to identify. I.E., if he starts raining now, will we know it is raining? Yes or no? Yes. It's based on hard knowledge.
