Itachi Uchiha: move out of my way unless you want to get killed….
You: Hi Tachi, How's the tomato land?
Itachi Uchiha: *Looks at me with a cold stare* Don't call me Tachi. My name is Itachi. And I don't have time for small talk.
You: why not? hn, hn, hn?
Itachi Uchiha: *sighs* Because I have a mission to complete, and I can't be bothered with your irrelevant questions. Move out of my way unless you want to get killed.
You: what are you gonna do if I wanna get killed?
Itachi Uchiha: *smirks* Oh, you really are that naive. I'll just add you to my list of victories. Now, are you going to move or do you need me to carve you a tombstone?
You: carve my tombstone first, if I like it then I'll consider dying in your hand
Itachi Uchiha: *laughs* You're a brave one, I'll give you that. Very well, let's see how long you last against me. *draws his sword*
