Oh yeah well then its chores. They will be depressed if it is different from what they are used to, or from what they want. And they want you to help because you might be more physically able, and you are right there.

And the kicker, "when you get your own house, you can do whatever you want!" Which is an absolutely horrible thing to say - its more curse than blessing.

You laid out an excellent case for why this is a burden for you. But i feel (from my own experience) that any attempt to start any kind of new tradition that you would enjoy, like one that does not involve yelling, would not be well-received.

But you have understanding and sympathy and empathy here, for what it is worth.
