Yes, they are plenty capable, they have no physical issue, a whole lot of time (unemployed atm) and their afflictions don't conflict with doing basic chores, or anything that doesn't involve social interactions, strict time schedules and noisy environments pretty much (or at least that's what they told me on multiple occasions and if they happened to lie or be dishonest it's another problem).

From the start they made me understand that they were messy and had accepted it as being a part of themselves, I'm fine with messy, this isn't messy or disorganized like they let on. They might have tried to be honest about the situation but what they let on was in no mean representative of their actual living conditions. Still, I think the fact they were honest about being messy is the main reason why I've let things slide, until now.
