A friend of mine, who I know for a fact has cheated on girlfriends in the past, has just posted this on Facebook "If your girlfriend is gorgeous and loyal, why flirt with other girls? Why cheat? its like throwing away a diamond and picking up a rock." To my knowledge he has never cheated on his cheated on his current girlfriend, but I still think this post is pretty hypocritical. I'm tempted comment on the post asking if he is posting it ironically. I also wonder if his current girlfriend knows he has a history of cheating.
