Dear Cash,

A simple work of advice for you as you read this, which I am assuming will be years from now. But you have already promised to take very good care of your sister. You have already promised to look after her and take up for her. You have promised to beat anyone up who messes with her or hurts her. You promised out loud. And you promised to her. 

Know this, if you ever get into a fight defending your sister you won't hear a single negative word from your dad or me. She needs you. She needs you to watch over her when we aren't around. She needs you to love her and protect her. And you promised you would.

And a big brother should always keep his promise to his little sister. 

Love,

Mom
