Not a Key to a New Car
It’s nice to feel important every once in a while. Sometimes, your boss will go out of their way to give you a thumbs-up to show that you’ve done a great job. Other times, such as during Christmas, your boss will gift you a mysterious key and a note that tells you how important you are to the company.
So, what does the key open? Nobody knows. It’s one of those old-timey keys that nobody in the modern world uses. Basically, the OP received a piece of metal and a note inside a mesh bag. Put it all together and you get a ton of disappointment.
