You haven't lost it, it's in your little pretty skull, hiding in the wonderful memories that you have :3 Here Monday, I was like "Oh I have an ide- never mind... it vanished" And I just lost my imagination for half of the day xD
Been there, done that. xD I was thinking about a book idea for an entire day, and when I finally plopped down by my laptop to write it all down- bam! Forgot everything.
Yeah, I once was about to write a little story for my char, but my brain just turned off and when I awoke from the derpyness, I was browsing on a website with kittens for sale XD
