I think that Friar Lawrence was giving great advice to them. They are just teens who need to chill out a little its not always go big or go home. Love Moderately was a great way to say it with out being rude or harsh.  It is easy to think its the end of the world when you are teen that is what we are known for. I think what he is trying to get a crossed is that there is a time and place and it is not now. I don’t think they will listen because again they are still very young.
