My sister is a terrible mother

My sister is 35, a single mother of 2, 14 and 7 y.o. boys. She does not work and is on welfare. My parents have paid off all of her debt (multiple times) and paid her rent when she was evicted for not paying rent. They have bought her 2 cars and pay her phone bill.<br><br>Last week, she decided to go to the beach with her boyfriend and left the boys alone for 4 days. She took them to stay with my parents for a week and then picked them up on the way to the beach, saying she was "straightening up the house" but really she left them alone again when she dropped them off a day before she got back. She got home around midnight and started "cleaning up the house" and stayed up till 4 am. She had to be up at 8 to get them to school. She fell asleep putting the 7 y.o to bed, then slept all day the next day. <br><br>We were discussing this and my dad said "she just needed to get away" I told him "that's why you need to get away from her" <br><br>I'm just fucking done with her. I'm tired of her being enabled and I'm tired of her kids being neglected. A 14 y.o boy cannot watch a 7 y.o all weekend. I'm tired of her getting all of this help and wasting it. Our Reno county is really good about helping people, they gave her a 3 bedroom house to live in for less than $300 a month! They pay her electric but she still has a hard time paying the rent. She refuses to do anything about finding a job. She refuses to establish a relationship with her ex so he can pay child support. I'm just so fucking done with her.
