When will we three meet again? In thunder, lightning, or in rain?

When the hurly-burlys done, when the battle's lost and won.

That will be ere the set of sun.

Where shall we meet?

Upon the heath.

There to meet MacBeth.

Why are witches always depicted as creepy old hags? Why can't they be young, attractive and alternative?

Being overly critical it's a bit jarring that only the witch on the right is moving her body. I would probably prefer all or none of them to move their body.
