Once the lights go on

Sometimes you rack your brain trying to figure something out yet your mind just goes blank. You may have spent a lot of time thinking about it and decide you just can't figure it out. Then BING as if a light switch had been turned on, you suddenly can clearly see the answer you were looking for. Although you thought you had stopped thinking about it subconsciously the search was still on. And when the answer was found, your subconscious turned on the switch so you could see it. Hopefully you wrote down the recipes for your Thanksgiving favorites, because it's time to do the last minute grocery shopping.  And even your subconscious may not be able to find that special ingriedient. And it won't taste like you remember without it.
