Cruel words are weapons? is a metaphor?

the tone of the passage is sympathetic to the forbidden love of romeo and juliet. the nurse plays a significant role in the play. she is responsible for making their meeting again possible. additionally, there is a sense of warning in the choice of words of the nurse. she seems to be authoritative when she calls romeo "scurvy knave", and at the same time the fact that she addresses to him as "sir" reflects respect. the nurse is "vexed", this word describes her confused state of mind. on the one hand, she finds romeo a fine and eloquent man, but on the other, it is thought that man's nature forces men to try to trick women.  

the teacher i would like to have must be a kind, caring and understandable teacher. she should be interactive with us and always plan fun activities to in our studies. she should be a teacher who would correct our mistakes when we do something wrong and guide us if we are weak. she should always be strict if we do something bad but must be praising us when we do something good. she she not take any as her favorite in her class but take everyone as her favorite.

(i hope this will u if there is something send me a reply)
