I know most twins get along well and are not like little clones of each other. I was thinking it would just add a little something to the game if on occassion, a set of twins either liked or disliked being twins. Like the frustration of having a the character who likes to do laundry and drives you insane because he is always wandering off from what is really important - just something to make it more varied.
