My characters feel like my children to me. I think about them often and I care for them. It'd be cool if they were real and I could have an actual conversation with them. I would freak the hell out if they came to life, but it'd be pretty cool.
Oh I have a good science question! If stars are big balls of fires how are they burning out in space without oxygen since fire needs oxygen to burn? I dunno I might just be dumb but I've always been curious about it.
