You"ve said to watch my mouth, so you don"t have to make me regret it. Hah, and how are you going to do it? What can you possibly do to me, to make me regret?   Make me cry?  There are too few people left in this world I have tears to cry for.
Humiliate me?  Maybe if I cared for what you"re saying. Hurt me somehow? Break my hearth? For that you"ll have to earn my trust first. And this is not gonna happen. With this single word of yours, you"ve blown up your chance. Kill me?  Then it wouldn"t really matter, right?
