If you want to comment on a post on our website you have to do it through your Facebook account. It's handy and convenient. Lots of people are already logged in to Facebook so it's really easy to do.

However, you may not know that every time you leave a comment on our website, or any other that uses Facebook comments, it posts your comment to your Facebook.

She is so sexy, I would leave my wife and kids for one night with her!

His wife, of course, saw this on his Facebook and said:

My idiot husband forgot his comments are linked to his Facebook account. You don't deserve our beautiful kids and I hope your brother has room on his sofa because I'm having the locks changed.

So there's the lesson. What you write could come back to kick you out of the house.
