You want something different, and then when it starts showing up, what do you do? 'Eh, that doesn't work,' or 'I already know that,' or 'I've seen that before.' Uh, news flash: NO, YOU HAVEN'T!" Marty is looking at me like my high school English teacher did when I tried to correct her and I was incorrect myself.
