Your brother Josh

You are flattering yourself maybe a bit too much about your new martial abilities, and this provokes your brother's reaction. He is 5 years younger than you and looks way weaker. Nonetheless, you know that he's been practicing MMA in the junior category for years. "Sarah don't be ridiculous", he says, "In ten months you have learned just some basic moves. I bet that you can barely defend yourself in a real fight". This remark pisses you off "Shut up Josh!", you say, "I don't know what would happen in a real fight, but I can still spank you at my will, so piss off and bring me a coke". He is like slapped in the face by your answer. "Do you realize sister" he asks "That I'm better trained than you? Do you want me to kick your ass in front of everybody?". The people around is now looking at you two in silence.
