How would you react

I would probably be suspicious because sometimes people will say things to start a disagreement between you and someone else on a just because they can be mean and vindictive. Question is how well do you know your friend? Can you trust them? also why would you even consider what someone else says your friend did unless you know that is something your friend would do. Not necessarily to you but to someone else. Otherwise, that message should be dead in the water. In other words, mission failed. You can’t go on what someone else says but what you can do is pay closer attention to your friend because even if they don’t say nothing, they will show you how they really feel believe me I know.
