“…they stumble that run fast.”
This quote is related to Romeo and Juliet by Friar Lawrence saying that they are moving to fast for any good to come. By that I mean that in order for them to have a good marriage, they must slow down and get to know each other as the have only fallen in love with their looks not their personality. They have only known each other for a couple of hours and like the hare and the tortoise, slow and steady wins the race but in the this case slow and steady wins love. They are going to stumble and fall out of love if they try to speed love up, love is a very powerful emotion not to be messed with and need to be proceeded with caution. Sometimes when you start to stumble, you can slow down and return to an upright and balanced position, continuing at the same speed and you will eventually fall and hit the ground.
