out the front window

I am trying to imagine that I am someone else,
a grocer, an aerialist,
a young viola player who travels
around the country in a bus full of musicians,

but difficulty lurks at every turn.
I am not really sure what a viola looks like,
plus, I have become so used to being me
that I have become an assistant professor of myself.
