If I left the mess you seem to be doing for my mum when she came back from holiday she'd probably clout me one.
It isn't exactly nice for her to come home and tidy up your mess when you are quite clearly old enough to do it yourself.
Seperate all those clothes into dark and light bung all the darks in together and the lights in together (2 washes). 40 degrees spin cycle with some fabric softner in the small tray and the tablets in the big tray (if you put them in the drum then they can dissolve before they are needed so less effective wash). Then put them in the tumble dryer until they are dry, making sure to empty the filter between each operation of the machine.
Then put all your dirty dishes in the dishwasher, put a tablet in there and turn that on.
Wipe up any mess left in the kitchen and feel proud of yourself for reaching through the plateau of adolescence.
