Used to share a flat with a mate who had this laundry system:
Start with bin bag full of clean clothes – when dirty, item of clothing goes into second bin bag. When first bag empty, swap bags over.
Dirty, dirty little man.
A housemate of mine at uni just used to buy more clothes and shove the used ones in a bin bag. (I say “shoved”, what I actually mean is the dirty clothes walked to the bin bag by themselves…).
Once he’d run out of student loan and maxed out his credit card on new clothes, he’d wait until the stink in his room got too bad then take everything to the laundrette and spend the day in there, taking over every single machine.
He’d then repeat the process but with 4 times the number of clothes he started with. The guy had more clothes than all the rest of us in the house put together.
