Am I my Sister's Keeper?

I am so frustrated. Mary, my younger, rebellious sister, refuse to do any type of work. She has never lifted a finger in her life. I am always stuck doing all the household chores. I cook, I clean, I do the dishes, I fix the cots, I sweep the floors, along with trying to uphold my bed and Breakfast business. Please, do not take this the wrong way, I love my sister. I adore her in fact. I often wish I had the carefree spirit she exemplifies everyday. I just sometimes wish she would help out every now and then. I have practically raised her and pray that one day she will show her appreciation by helping me out and lifting a few of the burdens off my back.
