How can a person help get someone to quit smoking and how can i understand thought he might yell at another? -
Kathy,
Nobody can make anybody do anything, especially when it comes to an addiction. Only the individual can make the decision for himself.
With regards to the rest of your question, I-m not really sure what you are asking. What do you want to understand, and who might he yell at?
Don-t try to make someone quit smoking. It will just annoy the crap out of them. A friend of mine said he would quit when people stop trying to make him quit.
