Sometimes in life you make a judgment call with the best of intentions, to help someone or to foster goodwill, and it all goes wrong. Sometimes a friend will tell others their version of what you did and then no amount of explaining on your part will make things right. This leads to discouragement as you realize that the thing you did last is the only thing that counts and that not all of your friends really are.
So, the best course of action in any group or work situation is to just follow the rules to a T (as long as they are not immoral, illegal or unethical), maintain a cordial, gentle aloofness in your friendships, and keep your mouth shut as much as possible. Not the happiest way to live, but if you're going to be hung on the gallows at least it will most likely be for a major crime and not for a victimless misdemeanor.
