A little girl and her father were crossing a bridge

A little girl and her father were crossing a bridge;

The father was scared so he asked his little daughter: 

"Sweetheart, please hold my hand so that you don't fall into the river."

The little girl said: "No, Dad. You hold my hand." 

"What's the difference?" Asked the puzzled father. 

"There's a big difference," replied the little girl. 

"If I hold your hand and something happens to me,

chances are that I may let your hand go.

but if you hold my hand

I know for sure that no matter what happens,

you will never let my hand go."
