is not fair for me

today,i felt unhappy. i thought my mom could not understand me. she told me that i should not be quarrel with my brother. my little brother who only two year younger than me. why? why i have to? so sometimes i felt blood-relationship is a bad thing. and sometimes i really hate him, a 22year boy,who should be able to take care of himself. i think i am right. as a sister, i have responsibility to educate him,right? but the problem is, he dose not trust me. he thinks he is right. so, we always argue with each other, for example, we live outside,but the whole rubbish, that i must clean by myself.i only want him to help me. but my mom does not understand. she thought it was a little thing, i should not argue with him.he just a little boy. a little boy? i think it is not fair for me.and i took the clothes to wash with the machine,of course, i need to pay. but she thought i was luxury. hey,in my room, there is no balcony. i need the washmachine to dry my clothes. moreover,i just use the machine one time a week,at most two times. i think she hurt me. i really feel unhappy at this moment.
