Imagine for a moment your best friend. She is going to get married to her big love.
A few weeks before the wedding you see the groom with another woman. They seem very very close. Actually it seems that they have something going on. You do not know all the facts, but your gut feeling just tells you that this guy is cheating on your best friend.
What would you do?
Would you quietly sit there and let her do the (in your opinion) wrong thing? Would you let her marry the guy? Would you shut your mouth?
Or would you stand up and talk to your friend, even if that could mean the end of your friendship?
What would your decision be?
Sometimes, standing up and voicing your opinion can be very much NOT appreciated, but in the end could turn out to be the right thing.
