I heard country singer Kellie Pickler sing a really heartbreaking song about leaving her small town and family behind. There's a line towards the end when she speaks directly to her mama and lets her know she's alive and well in Nashville, Tennessee. She can barely sing, and you can tell she's really emotional and crying. It's a true story, so I figured she was just overwhelmed by the memories.
Two weeks later, I heard her performed the same song live on another program, and sure enough, she started crying again at the exact same part in the song. Now I'm sure it's a cry break, since she does it every time. I'm not saying the emotions aren't real, but I'm saying the crying is part of the song itself.
