Background
I have found a new job in another city. While I'm looking for an apartment I will be living in my cousin's house.
I have never lived in her house before (and I have been at her house for the weekend less than 5 times) but we talk online regularly (more than once per week). I know I will certainly be expected to help. As someone on the autism spectrum I sometimes have trouble realizing when/if I should help. This leads me to be extremely tense when I think there is some unspoken expectation going on and I would like to avoid that. I would also like to avoid being seen as rude if I don't help by myself when I should have.
Question
How can I ask my cousin for specific house chore rules that I should follow?
I would like it to be more of a discussion than just a list of things. Everyone has chores that they like/dislike more than others and I would like to be able to say:
I don't really like doing X, would it be okay if I do Y instead?
Details and clarification
My cousin is married with two young kids (a 3-year-old and a less-than-one-year-old).
My cousin knows I'm on the autism spectrum (I told her one month ago) but I don't know how much she knows about this topic.
Why did I decide to post my question here:
I never did something similar before and I'm afraid at how she will react (finding me weird, thinking that I just want to do as little as possible, etc...)
Also, I'm not sure about how and when I should bring the topic (I only now that it would be better in person).
Also, if you have a list of chores I should talk about, that would be nice (I'm afraid something will be forgotten otherwise).
