6meh.1.1 Decision-Making model
State the decision
You're friends (including someone you have a crush on) which they think makes them "grown up."
List the options
I can start smoking two, I can ignore it, I can tell them to stop, or I can stop being friends with them.
Weigh the possibilities
If I start smoking I could get un healthy, if I ignore them they can get unhealthy, if I tell them to stop they might but might not and could stop being friends with me, or I can stop being friends with them I would be lonely.
It is important to me because I could loose my friends and they are making a bad decision
Make a decision and act it
I would tell them to stop and making good decisions is what makes u "grown up," not smoking and it's a bad decision to smoke.
Evaluate the decision
It might make them stop, might not, but it's the best thing to do.
