Dogged research reveals something you always suspected to be true. Unfortunately, divulging this information is going to result in someone getting hurt. This is one of those times when you have to ask if it's really worth it. Are you sharing this information because it's the right thing to do, or are you sharing it because it proves you were right all along? Truth and friendship don't always mix, and sometimes it's better to withhold than reveal. But knowing what you know doesn't have to make you an accomplice. You're still free to nudge, wink, and hint until this person discovers the answer for herself.
