Whose doing the dishes?

Here is where the good sister genes come out. I have tried that tactic before and since my sister's husband is away for work she will eat cereal or like I said forget to eat. So not cooking for her means most likely she wont really eat. She does work a full time job so I get being tired and just wanting to relax. But I too after being around the spaz all day would love to just chill. The dishes have always been a battle for us because that was her husband's job(which will be his job again in a month). But seeing as how I cook I would think she would step in a little more and help with them. I mean even putting away the clean dishes would help too. Every day is a challenge I guess and you have to just except it and keep moving.
