My sister is always trying to get out of cleaning up the house. Sometimes, she bribes my brother by offering him candy to clean her bedroom. Other mopping the kitchen floor. Yesterday, she swore that shed tell Mom that I got in trouble at school if I didn't start washing the floor. When she isn't able to coerce any of us to do her chores, she pretends to be sick so that Mom will feel sorry for her. A sudden terrible headache usually gets her out of the dusting or mopping.
