This has happened to me far too often. There’s nothing so frustrating as having the whole story in your head and not being able to capture it. That’s my best friend Mary on the bench with me, by the way. She knows about all my writing woes, and yet she still puts up with me.
Love it. Happens to me while I’m driving with no way to get it down. OR as I’m dropping off to sleep and I know the minute I get up and fire up the computer, the story has retreated deep into my brain.
Don’t ya just hate that when it happens? I get a lot of ideas in the shower, so I’ve learned to keep a notebook nearby. But I also have to remember to towel off first or all I get is a messy, runny blog of ink instead of notes!
