I think that friar Lawrence  uses metaphors in act 2 scene 4-6 of Romeo and Juliet like  the sweetest honey is loathsome ( hateful) in his Own deliciousness by which I think he means that the honey hates its own taste because people keep  picking on him in the way that they eat him, I also think that he links this to Romeo and Juliet telling the audience that Romeo an Juliet should slow down in there love.
