Do you have a song you’re embarrassed to have an emotional reaction to, but you can’t help it? Mine is Martina McBride’s “This One’s For the Girls.” I hear it in the car from time to time, and I lose it every time. Extra losing it if I’m driving, music-video-style, past first a group of teenaged girls, then an older woman walking briskly, then a middle-aged woman with her dog. It makes me feel all connected to all those other “girls,” even the teenaged ones who usually grate on my nerves by shrieking and shoving as they walk along, giving sidelong glances toward the road to make sure everyone’s watching.
