Timing for Book Delivery

Dear Self-Publishing Author,

Thanks so much for your immediate response to my 'congratulations, your book is available for sale' email.

When I explained to you on Monday that I couldn't ship you 50 books by Saturday because it takes 6 business days to print them, I didn't expect that you would think that I had so much control of space and time that I could make this happen.

I hope you understand that while we can rush the printing and delivery, my control over space-time is so tenuous that these might not make it to you by your deadline.

I, for my part, will work on bending time so that next time we will be able to meet your entirely reasonable deadline.

Sincerely,
Aspiring Time Lord
