I think Friar Lawrence is trying to tell romeo and juliet to take their relationship slow. I think this is pretty good advice because if they take it slow they won’t get sick of each other as easily and if they’re apart more they’re time together would be better. Since romeo and juliet had only met less than 24 hours ago and decided to get married I don’t think they will take this advice. They are not very moderate people. They know they should not be getting married because their two families hate each other, but they do it anyways in secret. They will either have to live their lives together in secret or tell their families.
