Friar Lawrence tells Romeo to love moderately. You should never take something you like and do it too much, because then it doesn’t mean as much. Lets say that you have a really great song that you like to listen to, have you ever wondered why you eventually don’t like that song anymore, it is because you listened to the song too much. I have a couple of CD’s that I don’t really like to listen too anymore, because I listened to them way to many times. When I listen to them I still like them but there is that feeling that is like it’s boring. My brother understands that, so he only has listened to his favorite song a couple of times, because he doesn’t want to ruin it. Friar probably knew that Romeo and Juliet were extremists and would ruin their love without great advice. He tried his best to make it work, but I would assume that they eventually ruin their love, because they can’t do anything moderately.
