How do you restrict Facebook postings so that *only* your friends see them, and no one else can?

In other words, how does on make sure "John Doe" sees what you post, and not John Doe's friend, brother, sister, wife, high school buddy, and all of *those* people's friends, wives, brothers, etc? lol
It would freakin figure, Abraxus. That is what I feared... oh well. Leave it up to FB....

Go to Privacy Settings -> select default to friends only.

when you create the post, click the privacy selector to choose who can see it

but once one of your friends clicks like or comment on it, then it is shared with everyone else on THEIR friends list too, and there's no way to turn that off
