Cry on, emo boy. Comparing your situation to this woman's is comparing tomatos and cheez-its. From the looks of the letter, the mom is NOT expecting extravegant chores to be done on a daily basis, she is BEDRIDDEN, and the husband is picking up the majority of the more time-consuming chores.
What is with you people? Seriously? Is it so bad that this kid is being asked to sweep, dust and mop every so often? These things are so basic she should be doing them out of habit, bedridden parent or no. Which means any argument between her and her mom should not have happened in the first place.
And honestly? If you were as much of a wuss about chores as this girl is, I do not blame your mom for freaking out on you. If you weren't and your mom was really unreasonable, then that was totally uncalled for and that's a ton of stress on a kid. But I can only wonder, considering there are two sides to a coin and you're sticking up for the little whimp that, apparently, thinks picking up a broom will condemn her to a life of company with dustbunnies.
