You area a coward if you can say yes to the following:

Do you have other people fight your battles for you?

Do you pretend to not know anything when you and the person asking know you do to stay out of the confrontation of information?

Do you hide behind people you have more authority than you?
i.e. Are you the Peter Pettigrew to their Voldemort?

Are you constantly making excuses?

Do you never confront others because your afraid of the truth?

Are you afriad of the truth about yourself?

If you answered yes to more then 2 of these you are a coward. But don't be sad. Everyone sees through your cowardliness and sympathizes. Sorry you're an epic fail.
