!SLAP!

All I seem to be able to recall is talking to my Dad, and my brother pipes up and says an insulting lie about me.
So, I step forward without even planning and SLAP him! I tell him not to interrupt and not to bear false witness against your brother, and your elder. (I am the oldest)
He says that that was a good slap, and I am right. He is very conciliatory and happily surprised. He is finally seeing the truth about our father.
I turn back to my dad but I see him running out the door. Before this he was pretending to listen with a smug look on his face.

I am winning! :D
