Negative number tales

I would like you to write a Math Tale. What is that? These are short stories with a problem to solve. What I suggest you to do is to write a funny math story with a simple problem to solve about negatives. Use negative numbers and negative situations (ex. Temperatures below zero, loans, money, debts, lifts…). Work in pairs. Include your names and stories as a comment, and, of course, solve your problem!

You can see more examples in http://mathtales.ca/stories.html
And here you have a useful dictionary
You can start with: ONCE UPON A TIME... or LONG TIME AGO...
