thanx, my brother and i have an extreemly emotionally abusive mother and he is thinking about getting the phrase "Et Tu Mater?" tattooed on his back with some something that looks like a stab wound (get it? backstabber..) i think it's a bit extreem but it's his body...

Might I suggest something eraseable?
