why must i do housework every single day?! EVERYDAY when i reach hm, whole chunk of things are waiting for me to do

1. pack the house
2. boil water
3. take down laundry
4. fold clothes
5. wash clothes

arghh!! and the worst is after work. when i reach hm ard 1am for weekday and 3am for weekend, when i still have lesson from 8am to 4pm! totally worn out but yet i still have to face all these :( My parents said i care too much as in i am over particular over small thing. wth! without me nobody will wash and boil water for U all! my elder sis is the WORST! never touch a single housework in her entire life! After her meals i will be glad enough if she washes her own cup and plates. It will be more than enough. BUT.........argh! i dun wan mention it! My dad always say she gonna be SINGLE for the rest of life. serve her right!
