Rant. Being nice. How would you tell your parents to stop being nice.?

Well my parent are from El Salvador too and i know perfectly what you mean, look when i was small, we use to live in this garage in the ghettos parts of Los Angeles, when my dad's son, my half-brother came in with his girlfriends....they didn't even ask permission to stay, well anyways my half-brother was a wife beater....and my sister and i were not used to seeing that like at all, but my dad always liked him more than me and my sister...so my dad wouldn't say anything.....we were small i was like 7 years old, later on my dad's other younger son, came illegally from El Salvador because they threatened to kill him and he was a total junkie...like he was on gangs and drugs 24/7 but my dad didnt say anything to him....i think my dad felt guilty that he left them very young....but any ways, we ended up moving to another place and they went along....getting into more trouble my other half brother, the wife beater got like 4 girls pregnant and didn't want to recognize his babies.....the other one was in drugs and gangs still....until we moved to another house and they moved away....little did i know what would happen next....my dad has this sister, my aunt...she has 4 kids and they got kicked out of their house because they lived like pack rats....so they ended up living with my dad's other sister which is a lot wealthier they have a big house and she is the mother of my favorite cousin...well the pack rat aunt ended up living with her for like 5 years and never even bother to look for a place.....my cousin use to tell me that they were getting fed up with them because they were just too dirty....than another cousin from El Salvador came to live with us, we didnt even know her...she came to live with us and she brought with her, her husband...and her two kids, but they did came here legally....we fought with her because she was just evil....then my pack rat aunt, fought with her sister.....her sister kicked her out with no compion together with her 4 kids....and where do you think they went to live with? man with us.....they lived with us for like one year....i felt just like you...fed up and about to scream at their face...i was about 13 when they moved with us, my mom, dad, sister and i were always tense about it ....well they were very dirty and inconsiderate....and very selfish...but then they found their lame *** apartment and they moved away....we ended up moving houses too because of them....we moved really close to them...and they use to visit us EVERY FREAKING DAY....i was so tiered of them...we lived there for like 4 years until we found another house far far away in a good neighbor hood and it was like a dream house big and everything upper middle cl ....and we been living here until now, and it was the first time i got my own room too....now im 21.....last year my aunt from Chicago (my mom sister) came with her 3 kids...and they were somewhat annoying to but they were clean and everything....but i told my mom...THAT IS IT, PLEASE DON'T INVITE NO ONE HERE ANY MORE...and she AGREED LOL
