Came up with this while reading Dorothy Parker on the flight home from Montgomery AL:
All my wisest friends have told me
If you'd save yourself distress
Keep a close watch on your heart
Be the one who loves the less
Love well, my friend, but not too much
So they tell me that it's best
To lose your head but not completely
Be the one who loves the less
If you keep your feelings penned up
Slightly distant and amused
You're much more likely to end up
With your heart just slightly bruised
This is what my wise friends tell me
Thinking of my happiness
Yet I think just one more time I'll
Be the one who loves to excess
