Of course it’s no monotone: Sometimes I might write about Sisyphus and sometimes I might write about drool (and sometimes I might speculate whether Sisyphus drooled while pushing the rock up that endless hill). By that I mean your short stories might have a female narrators, male narrators, be set in a tiny town one time and in a howling metropolis the next. But you still must find the voice—your voice—for that story.
I like to write essays that often take a humorous slant, but at the same time, that isn’t the limit or restriction I put on my own expression. I published a piece on not actually knowing my father despite my years with him, and another that discusses never finding out what happened to my high school girlfriend after she vanished in Colombia. Both had a tone of pathos. That pensive tone is also one of my voices, and its sobriety doesn’t cancel the chiming of my comic voice. So your voice might be part of a choir.
