i cant stand it.

i am always vowing never to help the sister change her bedsheets ever again, after we quarrel.

but i always continue to do it in the end. bcos i just cant stomach the thought of all that filth accumulating on her bed, which is beside the window and so naturally collects more dust and dirt than mine.

and also bcuz i know she never does and never will do it herself.

to think that she doesnt even sleep on it on weekends! yet i still change it for her on a regular basis. oh crap.
