El jefe likes to sing to me, as I've mentioned. He generally picks songs from what I call the romantic era of popular music composition, when songs about love, love lost, wishfulness, regret, longing for and appreciation of the loved one were the voice of the era, a seemingly more gentle, kind and thoughtful age than ours.
In our harsh, hardened and brutish era, people mock such music, dismiss it with a contemptuous sneer and will not listen to it. But I do. My husband does. And we sing it. Sometimes we sing duets, but he is the much better singer so I usually just play accompaniment on the piano.
I wonder how many husbands sing to their wives. I don't recall my father ever singing to my mother. I suppose it's not common. But mine does to me and I like it. I surely do.
