My Precious :)

Its like a throbbing piece of me,
kept outside of me,
An organ on display,
I worry each day,
More important than my heart,
My most precious part,
Like a dew drop on my palm
Should come to no harm,
Take my spirit, you may
But not a finger on it you lay,
My biggest weakness ever
Giving me strength, somehow, forever,
In darkness, light itself it will be,
Yes, I am talking about my family.
