Not can they, but do they.
My dh is away for a week and I've had a shock how much in terms of washing he does!! It's non stop, we don't have a dryer and the weather is crap but it's constant.
Then I suddenly think, there's 3 other adults in the house (DC between 20 and 25) and I'm washing their skids when I could be slobbing around in my room like they are!
I'm thinking about buying each a basket and a small drying line for their rooms and leaving them to it?
Same with food, they're rarely in for meals but I've found myself constantly consulting them on WhatsApp and co ordinating my life in order to feed them, when I could just eat pizza alone.
So do yours fend for themselves? There's always food they can cook and washing tablets etc but aibu to think at these ages they can take responsibility for their shit? They do all pay keep but minimal and when I say they do nothing around the house, I absolutely mean nothing... They all work, but so do dh and I and I just am thinking, why on earth are we doing everything...
