So why oh why.....

Do I feel the need to write when my sister acts all retarded????? OK some back ground here. She has three boys she's 27 and her oldest is 8. When she got pregnant she was living under my mothers roof right? When you live at home with your parents unless you help pay rent they expect you to live by their rules usually correct? OK so my sister does none of this of course then gets annoyed with my mother for leaving my sister to have to deal with the consiquenses of her choices and actions. My sister gets pissed off cause 'mom isn't helping her out, and abandoned her and her baby'. Mind you my sister had the baby daddy living in the house all that time. So my sis and mom are on the outs for a while and sis has to move out of state with the kids and the now hubby/babies daddy. They move back home to their home state mom helps them out as much as she is able. Well several times in my moms current relationship she's gone to my sister for help, looking for a place to stay when she and her STBX were on the outs. Each time mom has gone to stay with my sis she's done what she can financially to help her out. Well mom is in the position of living with sis again and the kids (all boys) are totally undisciplined and her youngest one has actually thrown stuff at mom and caught her in the face. So mom stays with my sis and is suppose to take what ever abuse the grandkids dish out. She's suppose to stay quiet and not discipline the kids in any way. Mind you my sister is a stay at home mom. All her kids are school age and she sits at home and does NOTHING for the six hours her kids are in school during the school year. She curses at the kids, and from what mom tells me she also has a habit of tripping them for no reason. So at the moment my sister is pissed off because my mother actually has the 'nerve' to tell her kids how to behave!!! This kind of shit totally pisses me off. Funny thing is my dad doesn't want to be around my sisters kids either imagine that!!!! Wonder why that is? My sister has no control over her kids and when she does things she tortures them for no reason. Now she doesn't beat them senseless but she doesn't consider her actions when she 'plays' with them then she gets annoyed because they all cry at the drop of a hat and her youngest one has the nastiest temper, he's extremely volatile, has a habit of hitting and throwing things at people when he's pissed off. Whew talk about some bullshit!!!! Seriously if mom is going to be living with them and helping them pay bills and buy food for the house she should have just as much right to discipline the kids as the parents do!!!! Especially if the parents aren't doing their 'job' and the kids are intentionally hurting eachother or other adults around them.
