“Smile Like You Mean It” by the Killers was released in 2005. I always took it as a song about putting on a brave face when you run into the ex or something goes wrong. We have so many other expressions to cover it, like don’t let them see you cry, never show weakness, and never let them see that you’re hurt. That’s pretty much how I was raised, to keep pain private, to always be tough and strong. Part of that seemed to be all about being manly, but it was also about not letting others take advantage of you through a perceived weakness.
