I think Friar Lawrenece was try to say don’t dive into anything to fast cause then you start expecting things and those things may not turn out how you want them too. I think this is great advice, he is just warning them that they’ve got to take things very slow so that they are safe then sorry. I think that Romeo and Juliet will not take the advice an at the end they will regret it and will take things to fast. I think they are not moderate people because they just bearly met each other and now they are getting married i think it was way to fast for that. They didnt take it very slow.
