One of the greatest challenges that teens are facing is peer pressure. This is because when teens are with their friends they feel that they need to do what their friends are doing. Or if one of their friends says hey try this they feel that their friends will think of them differently if they don't do it.
A piece of evidence is "You and your friends make dozens of decisions every day, and you influence each other's choices and behaviors. This is often positive — it's human nature to listen to and learn from other people in your age group." This evidence states that when you are with your friends that you guys usually make the same choices so if your friend wants to steal then you probably end up stealing if she/he asks you too. Same if you want to steal, you ask your friend and they probably will help you. I think thats its best if you surround yourself with the people that get your attention.
This isn't always good because they might be doing something bad and thats why it gets your attention, i'm talking about when the people who talk the people that don't have many friends.
Being at this age it seems like you should do what your friends do or you won't be as "cool" as them.If they are your true friends they will know when you are uncomfortable with something.
