Reading other people's comics is a dangerous thing. When I was a kid, it was common for any household to have some stack of comic books. I expected if I went into a home, even if I'd never been there before, that they would have comics and I got good at nosing them out. Also other kids would always bring their comics over to ours, to share.
So when I grew up, I had this memory of all these comic book stories I had read and yet I didn't have those comics in my collection. It's annoying having these half-memories of stories, yet not being able to read them. And, of course, I wanted to find those comics. I think I've found most of the DCs that I read back then, but there's several Gold Key, Dell, Harvey and the like that I will probably never find.
