washing your clothes in the sink is looooong...everything takes about a week to dry afterwards.
Ive been there, done that...got the t-shirt
I have to do it nearly every day, I could never be bothered to buy a washing machine, an at the moment I can't afford one.
Im not sure if Im even able to install a washing machine in my flat, with all the drainage/set up issues. I also definitely cant be bothered either way but always use the laundrette now, which just happens to be the complete opposite side of town, and I don't drive. hassle.
