The Lion and the Lamb

He STILL hasn't asked his parents so I talked to his sister and she gave me advice. She told me the proverb about the lion and lamb in latin. It basically says that the lion must pounce and make its move on the innocent lamb or it will never get to eat. She told me this because she wants me to be the lion and "pounce" on her brother or else we may never talk again. However, she also told me that I should wait to pounce until he has said that he can go. This is Plan A. If he can't, I will just take things easy and let him do the pouncing because I've already risked enough. This is Plan B, which I never want to have to resort to.
