Yes the challenge is to write a bedtime story in 50 words only.

The challenging part is being able to capture the readers imagination in just 50 words. Sounds easy but it ain’t.
Give it a go and don’t forget to use #adultbedtimestory as a tag

It's not because of the limited words. I will think about it what kind of bedtime story. Thanks by the way for explaining.
