I don’t believe you.

Maybe you don’t sing enough in the morning.
Maybe the reward for singing in the morning isn’t enough for you to put in the effort.
Maybe you’re not a morning person.
Maybe you haven’t warmed your voice up enough.
But if you really wanted to sing in the morning, I bet you could.
Today I heard two ladies sing an impromptu duet of O Holy Night. For the sake of it. Because they were in a big church and wanted to hear how it sounded with the natural acoustics.
It was a little piece of heaven. Truly beautiful.
And it happened at 9.05.
In the morning.
