Facebook has plenty of interesting features for users to exploit. One of these is the ability to note your relationship status. You can pretty much be any status that takes your fancy. However, this is not necessarily all fun and games. Some users take this seriously. The beauty of Facebook is that changes are instantaneous and your "friends" are sure to note any change in your status.
Now, in a tragic case in the UK a man murdered his wife in a "frenzied and brutal" knife attack because she changed her Facebook status from "Married" to "Single". The man has now been sentenced to 18 years in jail.
Perhaps one needs to think carefully before changing their Facebook relationship status.
