I CANT; I ABSOLUTELY CANNOT; THERE'S JUST NO WAY I CAN; ITS BEYOND MY CAPABILITIES TO DO SO; I'M COMPLETELY UNABLE TO PERFORM THAT TASK. I FIND MYSELF UTTERLY INCAPABLE OF SUCH AN ACTION. REGRETTABLY, I MUST ADMIT THAT I LACK THE ABILITY TO DO THAT. I'M SORRY, BUT I'M NOT EQUIPPED TO HANDLE THAT. UNFORTUNATELY, I'M NOT UP TO THE CHALLENGE. I MUST CONCEDE THAT IT'S IMPOSSIBLE FOR ME TO ACHIEVE THAT.
