This image is so evocative. I imagine her shouting at a little piece of straw that she’s startled by on a floor somewhere. Maybe she thinks it’s a snake. Maybe it’s like those cats startled by cucumbers – seeing something they didn’t expect to behind them.
I imagine straw was a bit more common to see in Shakespeare’s time. Maybe it gets brought in on the feet of a courtier who’s come in from outside, where the horses stand in straw. Maybe it lives on the floor of a kitchen and so makes its way into even the most ornate beautiful elegant rooms. And of course in my urban life, the more common straws are the ones in drinks and to watch someone spurn one of those enviously would also really be something to see.
