My wife and son were walking down the street when they walked by a parked car with someone smoking inside with the window down. We have tried to explain that smoking is not a the best personal choice. So when the situation presents itself, he feels he knows enough now to comment about it.
“Mom this man is smoking in his car. It will make it smell disgusting and then he will die soon.”
This information was correct but it was actually fairly similar to what his cousin has to say. Perhaps they have been exchanging information.
