Handiemail: Real Handwitten Words

And, they're hiring. At last, the day job I was born to work as a supplement to my fabulous lifestyle. Sadie Doyle would be proud. 

I completed my application, with the exception of a writing sample. I printed out their gridlines, put it under a piece of paper, and copied the sample text as faithfully as possible. It was a thing of beauty. 

I got all the way to the very end, and signed the sample letter with, 

"Handemal." 

According to their specs, this means I have to rewrite the whole thing from the beginning. 

Further hilarity: as I typed this, I spelled "faithfully" as "failthfully." 

Edited to add: Here's another thing. As I was copying the text, concentrating on my handwriting, and making sure my words and sentences fit within the line guides and so on, only checking to make sure everything matched (it's more like drawing, honestly), something sort of unlocked and woke up in my brain. It felt really good.  I haven't been able to find my magical purple journal for over a week now and it's driving me crazy.  My point is, long hand writing does something in terms of brain activity.
