What do you think of me not jumping at my mum's every command just because she broke her elbow?
That sounds painful for her. Why don't you want to help your mother when she needs it?
I'm sad she's broken it but I shouldn't have to do all the work.
I can see how you might feel overworked. It's good to help out your mom when she can't do her usual chores, though.
I'm an adult, I should be able to choose what I want to do.
Your mother would help you if it was you who broke their bone, wouldn't she? You should try making her more comfortable at all times until she gets better. She will heal eventually and you will be free of the extra work.
