What are ways you can turn down peer pressure?

Some ways to turn down peer pressure:

• Walk away- you might feel like a coward in turning down an experience, but you might be saving yourself from the embarrassment or a mistake that you'll regret later.
• Rainchecks- they'll think you'll be available the next time, yet you won't fall easily into peer pressure.
• "I have something better to do." Simple, saves time.
