Prompt No 21! We've come of age ;) And on that note, this week's prompts:

"You can judge your age by the amount of pain you feel when you come in contact with a new idea." - Pearl S. Buck

OR

A female character 'comes of age' in an area of her life.

You can post your flashfic any time, or do any of the prior prompts.
Background pairings are fine so long as the main focus of the story is gen.
