... I mean of course I can say no but some how that never works. What would you do if someone asked you to do drugs, or cheat, or steal etc.? What would you say, do, etc. I really wanna know so i can be prepared when it happens to me.
I think you're being pretty realistic about all this
You know it is probably going to happen to you sometime and you're trying to think of ways to say no that won't totally destroy your cool quotient amongst your peer group/friends.
You're right. It's incredibly difficult to just say no.
You might try to think about different phrases or actions that would allow you to walk away from a bad situation with your dignity intact.
One of the keys to it is to get yourself away from the situation as quickly as possible so there's no further chance for you to be persuaded more or to get into an argument about why you are saying no.
It depends on the situation and what you're being asked to do. Think about how you act with different friends and different moods.
Sometimes, it could be as simple as putting on your "uber" bored / "cool" emo face, shrugging, rolling your eyes and saying something like "This is sooo boring.. I'm soooo bored" or perhaps "meh... I'm just not interested" then
turning and walking away.
Otherwise, it might be putting on a peppy, incredulous face and saying "ZZZOMG!" and laughing out loud, adding in a teasing/jokey way "I can't believe you said that! OMG! OMG! No way! No way! I'm outta here!!" and then turning and walking away (or even running away in a funny, spazzy way).
Anyway, there are different ways to say no. Don't expect it to be easy. It's not. But lots of people manage to avoid the bad influences without giving in to peer pressure.
The important thing is that they walk away and don't get into discussions about why they don't want to
