When you are newly friends with someone on Facebook, Facebook notifies
your other friends with a title like “X is now friends with Y” on their
news feed! In most of the time, it shouldn’t look pleasing to you and
sometimes it could be embarrassing. When someone knows you are now
friend with someone, it may break your privacy. Unfortunately Facebook
didn’t make it easy to stop sending notification to others or not
showing it your timeline. Though, you can still configure Facebook not
to send info about newly added friend activity.
