When I post a comment on someones status, sometimes it appears on my other friends' news feed. I do not want that. Sometimes my friends see something they weren't supposed to see. Something that only my friend and his friends should have seen, not all my friends as well.
How can I prevent this happening? I know that it's a matter of my friend's privacy settings, but is there no way I can prevent this appearing on my friends' neews feed, since there is no way for me to know how the privacy settings are at my friend's page, which just posted the comment to.
