One of my friends started a rumor that I was outside some girls house calling her and telling her I was watching her. I was never in a situation that could even have been misinterpreted like that. What should I do? He is still my friend. I don't want to make him mad, but how can I get him to stop? When I ask him to stop, he just laughs, saying he heard it from someone else. This rumor is not true at all. Is there anything I can do?
