'Sally' is the hypothetical 'perfect girl'. She doesn't have many characteristics, but those she possesses are important.
They are (in no particular order):
- She loves you back.
- She likes to talk and listen.
- She enjoys arguments.
- She likes to push you on swings, be pushed by you on swings, and generally enjoys swings. .
- She is pretty in a 'DHM' sort of way.
These are known as the Five Points of Sally or 'FPS'.
A 'Sally' is a rare sight in the world.
