Banquo describes the witches by saying “By each at one her chappy finger laying upon her skinny lips:” Also he said “so wither’d and so wild in there attire, that look not like the inhabitants o’ the earth and yet are on’t?” The last thing he said was “you should be women, and yet your beards forbid me to interpret that you are so.” In my opinion i think Banquo doesn’t like the witches so he says rude things about them.
