I'm reading Frank Miller's new autobiography and he states that it was actually your idea to make a female Robin in "Dark Knight Returns." He says you even doodled a version.

Do you remember this - was it an off-hand comment or a more serious creative conversation between you and frank? 

Do you remember the doodle - if so, was it anything like what Frank used? 

Thanks in advance for any insight -somehow I'd never heard this before, even though I've read a million interviews with you and Frank over the years!
