Dear Jacques,
I've really enjoyed your time with the Devils and I'd hate to see it end with this season. The job offers lots of travel, a dynamic work environment, exciting opportunities for growth, management of a large and talented pool of personel and summers off!
Although i have no authority whatsoever to actually offer you an extension, I'd REALLY REALLY like you to stay. You're the peanut butter to our jelly. The chocolate to our mint. I'll be your best friend, walk your dog and mow your lawn!
Pretty please?
