How do I remove a Facebook friend or connection?

Uh oh, sounds like trouble in Facebook paradise to me! :-)

Fortunately, it's remarkably easy to defriend someone on Facebook, just a few mouse clicks. First off, select "Friends" from the top navigational bar:

Notice here that within the "Friends" area, I've also selected "Friend List". You'll want to do that too.

Now scroll around until you find the profile of the person in question. It'll look approximately like this, though obviously we're not talking about the same person! :-)

Note the link on the lower right, "Remove Friend". That's what you want to select. Click on that and you'll get a confirmation dialog box:

If you're really sure she should get the proverbial boot, click on "Remove Friend", otherwise click on "Cancel" and they'll never know that they were on the very edge of the abyss. :-)
