I believe it is harder to stand up to your friends rather than your enemy's because when you choose to face your enemy you have built up the courage to face the issue. When it is all said and done you won't have to deal with the collateral damage as you would with a friend. When standing up to a friend not only do you need to build up a lot of courage but you also get to thinking about the consequences of how you could hurt their feelings or ruin your friendship with them. It takes more courage standing up to your friends because they are people you trust rather than someone you dislike and standing up to them could come off as you are trying to change them. Both of them take a great deal of courage but standing up to your friends you also have to deal with the aftermath.
