From the book 712 More writing Prompts, this prompt was “Write a thank you note for a weekend visit where everything went wrong“.
Dear Aunt Mabel,
It was lovely to see you this weekend. Even though it was only for a fleeting second as you caught us right in the middle of a bank robbery.
It is unfortunate that, while we got away with the money, just as you arrived so did the police.
Hopefully see you again in 10-15 years.
