Mel
There's that Tragic side of you, Mel. He won't change, no. He's Ares, I'm pretty sure that if he's been this way since before my ancestors were born, he's going to stay this way. But you're always welcome to do what you can to not have to put up with him. The world's a big place, and although you're in the same family, you don't even run in the same social circles. You're in with the arts crowd, he's in with the... testosterone laden grunty crowd. Or something.
Point here is that you don't HAVE to deal with him if you don't want to. Every family's got its squabbles. Yours just involves a little more... epicness. And Epicness? Is now a word.
